Hey guys i have a 2004 silverado ext. cab with a 5.3, wheatley tuning, cat back, k & n air intake system, shorties headers. This truck is my daily driver, and i don't want to waste more gas. Can anyone tell me what to do on gaining more power?? I was think about changing the headers to (LT's), is it a good idea?? well i notice the difference?? if so where can i buy some?? Should i cam my truck?

Thanks

 

Lt's will get you more power. I don't know if it will help your mileage though. Maybe someone else will chime in. Lt's can be found from some of the sponsors ------>
