ive got an 01 H.O. 6-speed strait piped. it had an older superchips downloader on it when i bought it and i stacked a drag comp on it. it smokes like a train and lugs up to 2000 rpms then the edge kicks in. Ive heard that the smarty is the best one for low end and was thinking of replacing the old superchips with a smarty if it would help. i use my truck to haul so i dont wanna go too crazy. any thoughts?
