Well, got my feet wet with a quick tune on my new to me 08 Avalanche 6.0. I just did some quick stuff like disabling DOD, enabling Power Enrichment, disabling PWM on the TCC and disabling VATS.
PE was effectively disabled as it was set to work only above 8400 RPM! I also removed the delay of 3 sec and have it activate at ≥50% throttle. My butt-o-meter tells me it's giving more power. It was so bad before I thought it was swapped with a 5.3.
Since I'm towing our old trailer tomorrow to North Bay, I didn't want to mess with torque management yet. For a first tune, it wasn't too bad. Still lots to learn though.
