I'm Bran New to tuning and new to this forum. I just purchased HP tuners wanting to learn to tune. I have a 2016 GMC Yukon 5.3 that keeps going into reduced power mode when I try to bring on PE at 3500 RPM and 60% throttle. Factory is set to 5,000rpm and 90% throttle.
Everything else is stock settings except DOD disabled, TCC disabled in 1st and 2nd gears and TCC desired slip zeroed out.
I am Only changing a few things at a time and saving every file and I can flash back to the previous tune and it never goes into reduced power mode. The only changes made that are causing this problem is the PE rpm delay and Throttle enable percent.
I searched the forum and did not find anything that related to this question. I attached 2 files the one with PE and one without that is currently flashed to the vehicle.
Thanks for any help.
