I have a 2002 Camaro that I did a P59 Swap on to run Flex. I started with a tune from a 05 Avalanche, Trans Segment Swap for Manual Trans, 3Bar OS Conversion For Boost, and copying my previous tune exactly, my fuel gauge is reading backwards. Any help with what to change is appreciated.
I can't open your tune, but did you copy over the Primary Volume table? On a Camaro file it goes from 0 to Max, in a stock Avalanche file it goes from Max to 0.
