Colossus, I agree with you for your truck. However, try this. Get a straw and try to breath through it while you are running up hill. That's what the new engine designs coming out of Detroit are like. The FIPK has added noticeable power and mpg increase for my '02 5.4L. Gotta compare apples to apples.

BTW, I'd give my eye teeth if Ford would start selling a truck with a good ole high cube engine like they used to build. Had a '77 F350 with the 460 and a granny gear, and that thing could pull your house up the side of a mountain at idle.
