2002 F150 5.4L 4x4. Diablo Superchip. K&N

 

I am interested in getting a computer chip for my supercrew. Did you notice a diference with the Diablo chip? As far as cat backs go I have been doing some research the last few weeks andform what I seen they are pretty comparible in performance. It probably boils down to what sound you like and how they mount up. I am thinking about getting a Gibson dual sport but I guess I need to remove the spare tire.

 

The Diablo has worked out great. Acceleration and throttle response is improved. Shift point rpm and max rpm are higher. Increased fuel efficiency I have not noticed as motor is still tight (3500 miles) Take your time on install and follow instructions, especially on cleaning the contact points.

I am interested in results with after market MAFS, intake swirl plates and better exhaust.

Has anyone tried the Ford Competition Exhaust Manifolds?
