I just put on the KB with 3.2 upper and 4# lower. Got my tune from Sal today via xcal 1 and he instructed me to set the mafia on level 2. When I do this and load the tune the truck starts and idles fine but runs like crap. When you give it gas it just studders and tries to die. It runs fine on the old tune (ported eaton) and mafia taken off but won't hardly go with the mafia on. What could be the problem?? Other mods are ftvb, fluidyne HE, SBTB, CAI, NGK tr6 gapped at .036. He said to maybe drop the gap to .032. Could my gap be causing the problem?
