Ok I'm all confused now after reading all these post
I have a 06 1500 4x4 SLT with a 4.7 I love the truck just not really impressed with the power right now. the only mods done to the truck are a K&N CAI and 2" front leveling kit. my question is what is the best Mods to do to gain power but still keep it drivable? I know it's a truck and right now I can get between 15-20 MPG depending on how I drive and I'm happy with that not wanting to drop MPG down much lower.
