    I want it to be tuned as it should be..
    One of my friends send me the modified tune.. but on part throttle something weird happens with the throttle %, it goes up and down even if i keep the pedal steady, and that make the truck bounces.. on wot sometimes it runs strong sometimes not, it turns on 2 codes, intake airflow performance and tps, but im shure it has to be because of the tune

    Also--On other E92 SC tunes I don't see anyone changing the "MAP sensor scaler" beyond the stock #'s
    I see you changed many of the VE tables as well---I don't see this being done other than on dedicated race cars
    Same for the 2 throttle threshold tables
    I would try to set all this stuff back to STOCK and see if the throttle weirdness goes away
    Ramp in fuel factor is way to low---- I see and use 1.75-1.95
    Finally 12.10 -12.30 seems very rich for a SC DI engine--Most are around 12.7 which is considered VERY SAFE
