I am taking my crewcab to the track tonight and I am trying to think of everything before I go, it just has the 5.3 with a cold air intake flowmaster cat back and I just got done filling the tank with 93 octane and my hyperpac premium tune I am considering descreening the maf but I have heard pros and cons. Let me know!

 

Dont descreen the MAF. Why did you fill up with gas? That is going to slow you down.

 

What happens if you descreen it? and the track is aways away taking the family!

 

I suspect it might run in the 15's bone stock!

 

Well how did it do????????

 

SLoooooooow! 16.249 that is probably the slowest I have ever went on any track almost wasn't worth going but none the less it was a base line it was very hot out there and my buddy's stock trailblazer ss only did a 14.8. I have deciced that I wont go back out until it gets blown!
