Did the truck drive fine before you installed the new tuner? You could get lucky and have a few corrupt files burnt onto that chip or you need to starting looking at your truck for worn parts. Throwing more boost & fuel at a truck tax's other components like the hpop, injectors, turbo etc. If all these are not up to par then the hot tunes will not work correctly. If I were you I would pull the chip out and have the truck scanned for fault codes, this may give you a starting point.
