i took my truck to the strip for my first time and the best it ran was a 15.48 at about 88mph i was wondering if that was a normal time for my truck

08 sierra vortec max
cai,cat back,programmer and corvette servo 4.10s

just wondering what you guys think

 

seems about right to me

 

Get rid of the programmer and get a tune you might hit a high14.. long tubes and good tires might hit low 14s

 

yea im looking at the nelson performance tune im just waiting till i do but long tube headers on
