I went through the AutoTune VE tutorial this past weekend and bumped up C6101 by 50% (someone had suggested this step to avoid the "reduced engine power mode), drove the truck for 3 days and everythiing was great. When I drove in this morning and "got on it", the dad gum "reduced engine power" msg flashes and the truck looses power. Dang, I though I had fixed it with the C6101 bump up. Does anybody have any suggestions? Should I bump up C6101 another 50%? I didnt get on the gas back when I went through the tutorial because of the warning that the cats may be damaged if I do that. I'm running the stock OS and personal flashscan version of efilive (no custom OS, 2 bar, 3 bar stuff).
