I have the Superchips Cortex, Witch I bought from another member. I installed the K&N CAI Tune with it. I Have nothing to compare it to ( Truck wise) , but it was cheap, very easy to use and makes a hell of a difference over stock. All that I wanted. The 87 performance tune gave me gobs more power and amazingly quick shifts ( stock was soooo sloppy, now it just sifts like lightning) ( on the butt dyno) and the mileage xs gave me 2.5-3mpg better on the highway, with still a dramatic improvement over stock.
