Power is just "OK"

I bought myself a stock 2003 F-250 with the 7.3 PSD,automatic.It was well taking care of.Runs good but the power seems something to be desired and uses way more fuel than i thought it would.What i mean is that I owned a 2004 Dodge Cummins diesel with the automatic transmission and it had a lot more power and torque..The only mods on it were a 5 inch exhaust and some minor intake mods. I was wondering if I put a larger exhaust and got rid of the muffler would it wake up this engine(7.3) maybe put a chip in it? Any answers would be appreciated...

Intake and exhaust will not add much power, they are more of supporting mods. I would do a DIY intake ($40 ish) and cut the muffler off or put a walker BTM on there ($70 ish) then get a chip of your choice. I would go with a TS style chip with tunes of your choice on it. Good tuners are TW, Matt at gear head, Swamps etc.

There is no need to get a bigger exhaust. the stock pipe is fine, you just need to get ird of the muffler!

Just a basic 01 F350 CCLB SRW -Good from a far but far from good

Welcome!!!

Yeah, what he said...

Gauges... must have before any chip, good idea no matter what. Set of Boost, EGT, and Tranny temp with a piller pod will run a little over $300.

DIY intake... do a search on this site for details, but it's a cheap and simple intake set up. Cost about $40-50, and about 20-30 minutes to install

Exhaust... straight pipe the muffler, it's not really that loud, or go with a Walker BTM muffler... not sure on the cost, but range from free (straight pipe I had in the garage, I had the welder and torches and buddys with beer) to maybe $150 if you went with the Walker and had a shop do the install. The stock size exhaust is ok to 350-400 HP, it's the muffler that's the 'bottle neck' in the system.

Chip/tuner... I have a DP-Tuner, have for a year and a half. Love it. There are others out there that are simular... DP Tuner, Tony Wildman, good custom burned chip that is selectable will do well for you. My DP can be switched from stock to 40+ HP tow to 80+ HP economey tunes at any time, instantly. Heavy load, flat ground, cruse in 80+ econo, hit a hill, switch to 40+hp Towing tune... shift on the fly! I paid about $440 for mine with 5 tunes.

Good luck!

All said and done, you can get good reliable 300+ HP out of your truck for about $800.

Maybe easier to mod. And at least he didn't say Dodge is better.
Oh well, your opinion.

Well yea an 04 is gonna be faster than a 7.3. The intake and exhaust will help. That's all I've got done for now.
