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

With the new ECU flashed and the engine now running correctly, the GMC Yukon is carefully driven onto the Dynojet dynamometer. Before commencing any high-load pulls, the team decides to perform an oil change. During this process, they discover that the wastegate (a component of the turbocharger system) has broken, causing exhaust gases to bypass the turbo and limiting boost pressure. This necessitates a temporary repair to re-enable boost for dyno testing.

Goal: Prepare for dyno tuning and repair the broken wastegate.
