04 350 sd performance kits
does any one with a 04 sd f350 4x4 with a 5.4 have a performance kit like exhaust/ intake and like a hypertech prgrammer installed and if you do how much power did you gain ? worth the cost power and fuel?

I run a KN FIPK, Gibson cat back and a Diablo chip in my 5.4, I'll keep the chip and they can have the other garbage back!
The chip or programmer will do the most for you, as far as firming up shifts and a little hp gain, as far as Im concerned, the KN and the cat back were a waste of $$$$.
With my chip, you have to run higher octane fuel, and with no mileage gains and my heavy foot....well those $60 buck fill ups are starting to hurt.

I have to agree with yeti except for the fact that the gibson sounds awful nice. Couldnt stand constant stock exhaust noise. Could here me from all the way across the cornfield. sounded like big vaccum cleaner. can still here me but sounds much better

buggy,
Post this question in the computer - tuner forum, Ken (the owner of this site) will answer all your questions about this way better than I can.
I only run a chip at this time, made by Diablo, I haven't really researched any tuners yet.
