03 Sierra 2500 with 6.0L
what if anything can b done with the 6 liters to get better fuel economy? have a cold air, magnaflow exhaust and came with a hypertech tuner. want to get a different tuner for sure. any small cams add lil more power , better economy? different intake? open to suggestions.
when u take off from a stop hard, it feels as if u r taking off in second gear(torque management)? i would like to take the cats off to get lil more sound, as the magnaflow is quiet as hell. we do not have vehicle emissions so that is not a concern.
