Ok guys one thing I keep expirencing, seems to be hit and miss, not really any correlation between tunes or anything, sometimes I will flash a new tune, the truck will run fine, but then while driving normally I will go to grab more pedal and it feels like the motor goes into limp or something, to where only the first 25% of pedal movement has an effect on the motor, if I put it to the floor the truck will just slow down even further, downshift, and have no power until I back off to like 20% throttle, no DTC's either, if I stop, flash a different tune, then it wont do it again. WTF? any ideas? Like I said it doesnt seem to matter what tune it is it just like hit or miss. wierd.
