I've got a 1997 Chevy Truck with a Vortec 5.7 with an auto tranny and about 160,000 miles on the ticker... is my truck too old to tune? i pull a trailer every once in a while, but would like some more just everyday power... it's completely stock. stock air box everything... it's got some 285-60 bfg's on it and i'm just curious what you guys could do for me? or should i just leave good enough alone? i don't want to damage somthing this late in the engines life by tuning it now?
