I recently bought a Hypertech Programmer for my 2001 F-150 5.4l. I wasnt very impressed. The shifting improvement was great, but I didnt get much umph out of it.

Anyone WITH A 5.4l F-150 try this with the same results? Anyone try any chips? Diablo? Jet? etc....

I really want to hear what kind of experiences people have had with different chips/programmers/etc. WITH the 5.4l engines.

This is THE answer to all your FORD tuning...

Super Chips Custom Tuning (programmer) or FordChip dot com. The fella behind these knows more about programming FORD vehicles that Ford does, and that's the truth. Check out www.mercurymarauder.net or www.modulardepot.com if you doubt what I say.
