    Charger srt392 tuning

    Hi every one,
    I had issues when tuning a 2012 charger srt392 with dynatech longtube headers, and hellcat injector. The car have a e-flexfuel box with ethanol sensor for e85 running ( I come from France, e85 cost 0,5 dollar a liter, 95 octane gasoline cost 1,5 dollar a liter...).
    I tuned with ANN off, after a few tests, stft+ltft were begining to be good (I learned that GPEC2 must have adaptives resetted after each tune). However, after tried to change tire size, the car got few dtc?s codes... acc, fcw...speedometer will not work too... . I erase all dtc with a witech and it didn?t work. I had to disconnect battery for 30 min to clear those dtc and did an ACC Learning with the witech to solve all issues.
    But when I tried to log again in order to refine fueling, stft+ltft were out! Until -40%! I didn?t change anything in the tune and don?t know why it did that. Someone know why?
