Dont know. I got an 04 ext cab.
Mine went a best of 14.4 with good air, weight reduction, k&N, longtubes, dual exhaust, descreened MAF,wheatley tune, 3.42s and an open diff, stock stall, stock trans, stock heads, stock cam.Averages 14.6 most of the time.This is run on 26" tires, it would only pull a 15.1 on tahoe 20s with no weight reduction and a more conservative tune.
04 Silverado ext cab. 4.8, K&N, Pacesetter lt's, e cutout, slp loudmouths, Wheatley tune.
mine ran 15.7 with bolt ons and no tune, that no tune bit is killing me and i spun at least 50ft. street tires are a no-no

I've gone 13.8's stock internal in mine and have a friend that's gone 13.2 with a TR224. There have been several that're around 13.2 for n/a cammed 4.8's, don't know about FI.
Just a 4.8.......
Thats just proof of how big of a difference a live tune make over a mailorder like mine..
