98whitelightnin

does anyone know of the best xzt+ tune for a 98.5 auto.the truck has 150 jammers, 150 fass and an hd tranny with billet tc. i just took the factory tune off and replaced it with the comp tune, witch is supposed to be the most aggressive, actually i think it is slower off the line but did get rid of the surging and does have more smoke

high bid

try the 3000 tune.
