What Happens If You Turbo a 5.3L Yukon With No Other Mods? Lets Find Out! (Uncle Rob Hits the Dyno)

Watch on YouTube

What happens here

After diagnosing the fuel issue, the team realizes the current P59 engine control unit (ECU) is incompatible with the turbocharged setup and is known to 'brick' or fail during flashing. To resolve this, they drive to a junkyard ('Awesome Auto Salvage') to search for an older, more reliable 0411 (P01) ECU, which is known for better custom tuning capabilities. They identify the correct ECU by the blue and red connectors.

Goal: Replace the problematic P59 ECU with a more suitable 0411 (P01) ECU.
