i have a k&n cold air intake,mass airflow sensor,dual 2.5" flowmaster exhaust,hypertech(getting ready to get one from wait4meperformance).theres nothing really more to do to these engines.i would say to quit dicking around and just supercharge it.thats what im doing next.plus mine has a 6" lift with 35 inch tires.i get 16to18 mpg doing 70 on the freeway right now.so i think everything is set up right.unless the computer is lying lol.
