Not sure if it's right to post on this section but I have a 99 gmc Sierra 5.3 with the only mods I have done is k&n air intake , flow master and that's about it..I want to go faster and I heard maybe a chip would be good??? Or any other options but not trying to break the bank

 

only u decide if u wana break the bank. the faster u want to go the more $$$.. start off with a sponsored mail tune.. put some 4.10s.. thats should be cheap and make a difference..

 

I have no idea what that means.. I am a newbie to all this gearing and tuning stuff

 

Read through some of the stickys at the tops of the different gm sections to get used to all the lingo and parts used to make these trucks go fast

We have a few tuning sponsors on the right of the page that can hook you up with a custom tune
