and you can see their fuels i mean they're they're way too lean but it just it snaps there so quick but can you explain what injector duty cycle means people who may not be familiar with that it's just the easiest way to to explain it is it's how far the the how hard the injectors working the injector pulses and the higher the cycle is the less number of pulses it is so basically when you're getting up a hundred percent or more it's almost like the the injector is just wide open dumping everything it can dump so it's it's they're doing everything they can do they're just not being fed enough other informational sake what duty cycle would you say someone should put bigger injectors in like is it safe to run your car at 95 duty cycle if you're going wide open we have we've ran some of the ctsb's around 100 duty cycle but you've got to be you've got to be careful doing that it's not what i would really like to do i'd like to see them no higher than in the 80s somewhere like that um less is better but you don't want to get them so big that you're you know doing 50 duty cycle because then you got way too big of an injector somebody asked me that the other day and i was like well i don't really know what the good you know how much headroom you actually want to have is yeah i feel like 70 75 80 percent is probably i i would think i mean that's what what i've normally done i know everybody's going to be a little bit different and some tuners might say well that's dumb and you know you can run it on up to 100 i don't know everybody's different you know so and i'm not going to knock how anybody does anything there's plenty of ways of doing it but there's no way for us to get more pressure without uh without getting the voltage fixed i guess we'll try that first yeah we'll get that figured out that sure on the dashboard is for you by the way oh thanks man yep that's the monte carlo shirt that's right the car that did not do any damage to your precious floor not yet right i'm i will take this outcome over something breaking over a hole in the floorboard yeah hole in the floor that's good you know what we get to do now another relay wait what the fuel pump is not getting enough power we think from its little feed wire no yours is fine you did the fan the fans are the fans are great oh okay how are the fans working you did a good job you did great we're staying cool the fans are good they just don't have enough fuel yeah okay so the little wire that's feeding the fuel…
