What happens here

This project details the process of turbocharging and dyno tuning a GMC Yukon (affectionately named 'Uncle Rob'). The journey is fraught with unexpected challenges, including an incompatible engine control unit (ECU), a misdelivered fuel system, and a broken driveshaft. The project highlights improvisational problem-solving, such as sourcing parts from a junkyard and performing on-the-fly repairs and tuning adjustments to achieve performance goals.

it's either spinning or coming apart i don't know this this is literally a stock vehicle with whatever turbo you put on it because we have no map sensor no map we have no idea what it's doing the injectors are literally staying wide open like they're just opening and not closing periods so what are you doing are you just trying to freak out oh there's a there's a pcm on there what is it is it the right one it's time for the dino look who's back super tuner tanner's back that means we can put uncle rob on the dyno we're shopping you're gonna be doing a little bit of our pendant though yeah what i don't know what they're looking at they're doing some weird stuff we're doing some questionable things today yeah sure it'll be fine we'll figure out what the stock fuel limits are like we're ordering this stock like no no nothing done stock fuel rails stock engines like literally we have not touched the fuel system because um we want to put that money towards diamond jesus that's that's what we're doing no no that's not what we're doing but we are going to see what the untouched stock fuel system will do with a turbo on it first i just got to tack up this downpipe and then load this up this is probably going to be the most regular thing that's ever been on this dyno no i had a cobalt one time oh so we got we got a cobalt beat i'm i'm cool with that no this would be a fun one to test the two wheel versus four wheel drive with because it's so low power yeah that is your 50 50 we're fine i'm pretty sure the mechanical transfer cases are 50 50. yeah but yeah i wouldn't want to test that with the escalade but you know when that thing's going to make 400 on a good day yeah i think it'd be i've brought some f-150s up there and it was fine raptors yeah yeah we'll have to give that a shot then if the 4l60 survives let's go get this thing ready are you ready to dyno no already he doesn't want are you ready no he's not ready he's fired he's ready okay shop dog ready for the dino he doesn't like the mariachi you don't like the mariachi music good me neither anyway i just gotta weld the downpipe to the flange to anchor it down um i'm not gonna fully weld it because i'm not exactly sure that's where i want to keep it i'm just gonna tack it in a few places so that it won't come off yeah it's probably going to leak a little bit but you know what the exhaust dumps pretty much right down there anyway so it's inherently going to get fume leakage under the hood regardless so we're not a big deal this is just temporary until we can run it make sure everything's okay and then i'll throw it on the lift and you know finish the downpipe and connect the exhaust i just don't want to nail anything down until i know i'm cool with it because i want to make sure it's easy to get in and out once i flange and the secondary connection is already on there because i still gotta add a flex pipe and all that stuff but i'm just gonna kind of orient it where i think it's good add a few marks with a sharpie pull it off and send it home what time is it fire up the old cronies tack this thing down real quick hold on now you can weld oh yeah that's the can the famous can [Music] whoa inside gas tank is really low we're just going to throw like five gallons in here of some fresh 93 because i'm pretty sure i put 87 in it last time the gas is in it uh john's gonna go do some data logging in the v and i'm gonna see if i can angle this thing between ashton's truck and the 632 heat it up on the dyno over there let's fire it up this is a diesel habit like i turn the key and i let it sit there for a second for the glow plugs that aren't even there it's just when i see this interior that's just where my brain goes because my duramax looks exactly the same i'm gonna double check the transmission fluid level real quick because in bradenton at cooper's uh we put this csf uh transmission cooler in here and you know when you do that you lose some fluid in the lines and the other cooler and stuff well we put more in to move it around but we never really like double triple quadruple check the level to make sure it settled off where it's supposed to so obviously before we start gripping on the dyno um i'm gonna do that while this thing is gonna you know transmission is gonna melt at some point not just the future we want to actually see it do some stuff before that happens so we're not going to be super dumb with it we're have to go on a little side adventure real quick the weirdest thing just happened john lawson owner triple 7 got a call from a random doctor's office and said we have car parts for you here and he's like what and then they they said i have my name on it so you can even give me the phone and somehow my entire fuel system for uncle rob got shipped to a random doctor's office 25 minutes from here they said that the box had one of their doctors names and everything on it but when they opened it up they were like what the heck is all this stuff and they found the packing slip which had all of like my name and all of our info on it so they called john and that's how they got a hold of me strangest thing ever but i'm not exactly going to let an entire detroit fuel system just chill out at some random doctor's office all day so we're going to go get it um right now i've never had anything like this happen before all my stuff got sent to here random doctor's office and it has a re-label on it with like the doctor's name and stuff over the label that deechworks put there fedex must have just goofed something on their their shipping line through the wrong label on my box and you know thought these doctors needed some super neat injectors in a fuel pump system for a 2003 yukon got it now that's the important part you ready for the dyno i don't think he really cares do you feel at home no do you feel like my dad no i feel like an uncle well this is can you imagine me riding around in the backseat of this thing it's like eight years old watching you just move this thing around smell like an uncle wrong dude like if it legit smells like somebody's uncle if uncle rob had a smell this is what it was if youtube had sense it would enhance the experience of your videos i guess tanner read the tune on this thing apparently it has a p59 pcm which i don't know anything about he says they're not that good though but we'll make it work i don't know i'm just doing my best we're gonna find out together we're gonna find out yeah can you explain to the people what's going on here uh we're making unicorns happen what do you mean you know some ones and zeroes what's the p oh the p59 the tuning yeah it's got a p59 ec or pcm in it and it's just not a favorable one they're known for bricking themselves oh that's great i mean this thing kind of looks like a brick it's going with the theme it's brick colored is it ready for choo-choo noises yet yeah we're gonna put it on speed density and let her eat you ready for some sauce candy man are you ready to get back to yellow belly yes i am i was wanting to go last night yeah me too and then it rained a lot more than rain happened last night this is uh this is a big big deal a lot of people miss this break torque management yeah see that one yeah that right there will make them not do burnouts really that one to a zero will make this thing not do a burnout now it'll do a burnout even when they're stock even when they're stocked that will change it from being able to not go from a burnout to a burnout so you even if the bone stock you change that one to a zero you can do burnouts yes well seeing as we now have a turbo kit on this beast can't validate that theory one of you guys go try it see if it works what what happened he brings it i didn't break it yes you did what do you mean it won't flash it just says it's not found every time i was like i feel like we're working backwards detect protocol failed yup so now we gotta pull ecm out can we like go to a junkyard and put a 411 in it or does it not work like that it doesn't work like that you have to swap some pins and all kinds of stuff and it ain't worth it i don't know what this is this is probably old flat toeing stuff yeah this used to tow this used to get towed behind the family motorhome unit look at that custom ground up there hey this is for my fan dale watch out oh no don't tell logan she's gonna freak out why she loves that headlight she loves putting it back in it's like her favorite thing in the world ladies and gentlemen tanner sebs removing the pcm because he that's weird yeah that might be like the brake controller or something on there yeah that probably is that brake controller hold that we have no problem what's going on we got no problem it's okay rock you'll finish the race with them on the day of my daughter's wedding you'll come here on the day of my dino appointment with the first ptm and you would have asked me for my forgiveness i'm trying to do the accident but i'm trying to not laugh good you gotta like you gotta like get the frown on your face like you come to me with a terrible student and like you know be completely in like can't hear anything we need to take the ecu apart oh man i've never seen the inside of an ecu before really no i've never had to take one apart i've never messed with anything to gen 3. oh man you're about to see some cool that came out of me yeah souls of a damn hold that back don't let any of that touch it was crazy what came out the year that this car did baylor [Laughter] yeah maybe oh no it's like 2004. what year what no no what you were you wanted before this car is older than you yeah well this thing was probably built in 202 if it's an 03 model year what you're in a lot better shape than just foreign yeah we'll drag you through the salt for 16 years to see what you look like [Music] that could be a problem we are playing high stakes played for keeps high limits poker right here bro so now we see if it works still suddenly can't find timed out i can't off and try again it's okay you take your time i believe in you we believe in you i feel like she's getting revenge on me for putting them on the back burner for so long what are you doing having fun at yellow belly you should have been putting me together a month ago like well you know yellow bellies kind of a good time plus if i go watch you race and you break your car it doesn't cost me any money yeah wow this isn't good [Music] so it's 506. we found a salvage yard about 15 minutes away that has early 2000's gm trucks with pcms that we can go dig through try to find one but they stopped letting people in at 5 30. we can still get this done today but everybody is playing with dogs and little john is on task let the record show this little john is focused and no one else is that never happens this is a rare occasion you guys coming or what yeah all right little john is on task is he coming yeah he's already outside he got all the tools and everything he's going on an adventure my favorite truck here we go you got everything we need to get it out hey don't break the seat dude hey move the seat up we gotta i never have this many people in here i don't know what it's like to actually have friends okay last time i drove this thing it was not a good day yeah you freaking that's all right in the back seat was not a good day either that's when that that gopro went flying yeah this freaking gopro into the stratosphere and my trailer hitch went into my tailgate yeah so we made it to the place it's basically the alamo we have found like the alamo of scrap yards here and it's looking promising it's just a field of dreams out there dude let's get the forklift forklifts dunks we got a truck here um i don't think there's anything left of this oh there's a there's a pcm on there what is it what is it tanner is it is it is it the right one you'll find out what the suspense continues no trend blue dang dude look at this suburban two-tone custom exhaust here's one blue red blue and red so what we're looking for here is the color of the connector that comes out of it is blue and red is that an 0411 yeah okay so yeah blue and red is the o411 with something in green is the p59 that we're looking for um i don't think this is the one man this suburban this suburban looked like it was probably freaking sweet before whatever happened to it happened to it how sad how sad i don't like looking at that this is like really eerie looking import foreign foreign cars forwards forward dude every scriber i've been to has been like in the dirt and then stuff is just sitting there not like yeah this is a relatively clean scrap yard it's it's different look at this look at this car truck [Laughter] i don't even want to try we don't know who paved all of this like why is this whole thing all paved how did this i feel like this had to be something else first yeah why would they pave all of this just for a junkyard well i want to come back just to walk around yeah there's useful stuff in here for sure look at that is that a full grinder the rays of sunshine are pointed right on this glory pile oh my god bro look at that oh man i don't want to get that just to bring it back just to have a yard ornament yeah it just looks like cadillac has got the girl smushed down does this even have a pcm no how about this one okay red no it's red and blue and it's half missing anyway wrong body style let's see what this one has in four come on come on red and blue damn it that's a choo choo custom truck right here it looks like it went choo-choo into a freaking wall red and blue this one doesn't even have one i checked you see there's more over here did you just leave your truck idling all day all day long eight hours how many times has this happened twice eight hours i've been running well it happened around two okay well you know it it'd be like that sometimes but you know there was like nobody here he just left her truck running hopefully one of those works duel ecm is on your court one for each bank of the motor bmw style anything interesting happened we may or may not have found the right components we don't know yet how do we know what's the right one we don't we don't we don't that's the name we're gonna try that one this smells like diesel i keep smelling diesel all right where's the ecm over there the dmnr the dmnr the 5050 shot so from what i understand there's really no way to identify what these are conclusively unless you plug them in or you know exactly what it came from based on the vin number everybody's gonna hit the comments and be like there's a certain number on the back well if that's true we don't know about it because this isn't exactly something that happens all the time so there's no reason for us to know any of this so yeah we literally had 10 minutes to make up our minds okay are we gonna go look for one or not we didn't have time to look at anything otherwise we would have had to wait till tomorrow and you guys wouldn't see a video as quickly and it's on here ydnk is that what one of these says no no wow yeah so neither one will work it's gonna say green damn it no no what we didn't we can't figure out how to get it back in yeah that's a lie that was gonna have her do it because it's like her favorite thing ever but we made that whole trip for nothing we just yeah this stinks what do we do now come back here yeah i don't think we can dude i don't know we looked at every single one in junkyard was blue and red blue and red blue and red even tahoes and avalanches which are like the same thing as this but this o3 yukon for whatever reason decides to just not be that way what a shame well i mean it did just chill for like an hour could we try this the you know the goofy nonsense again i hope this works if it does then you guys got to watch us run around junkyard for no reason if it doesn't you guys got to watch us run around a junkyard for no reason because we got the wrong thing we had to try what just happened the battery terminal was loose are you kidding me no from your fans great freaking crusty battery terminals so you keep wiggle the freaking connector and it started working no look cleaned up you got to be kidding me maybe the the funky thing you did made it work we'll just i'm just i'm rolling away that you did something [Music] great success does that mean we're still gonna get to dine on this thing possibly okay walk together now oh one one step okay logan can you put that headlight back in we fixed it yeah it's funny all the stuff from bradenton is still in there i can never unloaded it really yeah all my welds are back there really yeah well that's where you've been hiding yeah did he throw up in there no okay good he probably smelled loretta [Applause] that's what all the boost is going to sound like if we just put it back on if you could in put it back on we're ready so it runs again what are you doing are you just trying to make him freak out it blow-off valve noises yeah it looks good look we're trimming fuel perfect no more mass airflow the o2s are working yes awesome ashton gave me one it didn't look the same as the other one but the plug was the same so i sent it anyway it looks good it's just trimming fast we're like good for the dyno now so once we get it on we'll i'll make a small pole see where we're at and adjust feeling from there sweet so now we get it on the on the dyno oh boy it's time once we get it up on the rack i want to change the oil filter because still got the old one in it because i figured i let it run for a little bit to catch whatever debris was in there controlling that hole and then put the new one on with the new oil so yeah [Music] he doesn't even flinch but you don't let two kids have a golf cart oh dang i go to the bathroom and they only wait for me super trainer tanner's on a mission uncle rob is entering the dino cell this is a monumental moment right here checking the transmission fluid level we got halfway we could probably use a little bit more maybe a little more i'm glad you just started doing this because like i wasn't really that pumped about it but he he dog cracked the filter loose and walks over there to get something else and we come back and there's like a puddle that's like dripping i didn't know we dropped like dude what's that and we're like oh no what is it and then he's like oh it's the filter like i didn't know he cracked it loose already yep i did shove her home dale uncle rob enters the dino for the first time in world history as a turbo truck you know what's wild i've been here for nine months now this is the first time any of my vehicles have ever been on this dino getting it all situated on the dyno how are you feeling surprised i didn't think it was gonna work i thought it was still a four wheel drive uh you know yeah none of those buttons were done well my uncle said from the power duration he had this he never put it in four-wheel drive so the current yukon xl denali he has now is two wheel drive and his justification was he never used it on this one he owned the thing for 12 years so it's very questionable if the four-wheel drive even it really works we'll have to figure that out later he looks like he looks like a high school kid that's like acting like he can drive in his mom's car like you just go into the garage and start wiggling the steering wheel not that i ever used to do that dude i did that in that truck so what it do i don't know none of them even had the dyno ready i mean like so you just did a a one pull just wait until the point where it starts to lean out then you're going to go bang and add more fuel is that what you do uh did you log that no okay we're just tuning okay dude i've never heard this thing it just made turbo noises it made turbo noise it did the blow-off valve thing like it's freaking we got ourselves turbo truck here this is cool i used to sit in this thing when i was a little kid jiggle the steering wheel pretend i was driving…
