What are your goals... ? Ever consider getting a custom tune?

 

custom tune long tube headers (pacesetter cough cough) 6.0l swap that will get started

 

Welcome to the forums man, the people here will help you out tons! I'd go with a custom tune, LT headers, electric fans, Trailblazer stall(for the price), TB Bypass( good mod, $3 at the most).
