I got the truck back from regearing yesterday. I tuned the truck today with the superchips cortex programmer. I gotta say the truck is freakin fast now! I raced my buddy's 07 classic 4x4 crew cab silverado with a 5.3L with programmer, 4:56s, 33" tires and i beat him 3 out of 5 times...not bad for a 4.8L with a programmer, longtube headers, 4:56s, and 35" tires...And another pic of the truck lol
