hey guys, i picked up an 01 tahoe in october of last year with 135xxx. i bought it completely stock all it had was an auburn locker and 373s. since then ive put an intake and an exhaust and electric fans. the truck is unusually quick/fast. i know the gearing with stock size tires would help acceleration a little bit but i know thats not it. im thinking maybe the guy i bought it from threw a tune on it and was afraid to tell me. how can i tell if this truck has a tune or not? the thing is the truck aslo has a misfire and even still its quick. ive ran other new tuned 5.3s and i still beat them. im just curious as to why this thing is a sleeper. thanks!
