What Happens If You Turbo a 5.3L Yukon With No Other Mods? Lets Find Out! (Uncle Rob Hits the Dyno)
What happens here
Back at the shop, the team attempts to flash the newly acquired 0411 PCM using tuning software (likely HP Tuners). However, they encounter errors, with the software failing to detect the PCM. After some troubleshooting, they discover the issue is a loose battery terminal. With the terminal secured, the PCM is successfully detected and flashed with the turbo-specific tune, enabling proper fuel and engine management.
Goal: Successfully flash the replacement ECU and ensure engine functionality.
