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.
