some say with a converter that stalls at atleast 2800-3000 you can knock off 4 tenths, with traction, with a completely stock truck. then gears is pretty much a gurantee to knock off a few tenths. this all depends on traction though.

 

something is definatly wrong in the tune! with an intake, exhaust, and tune w/ a 5.3 you should be in the low to mid 14's!!!! espically with a cam!!!
