2003 7.3 Upgrade

[deere4440]

First off I'm new to this forum so could you guys help me. I was wondering, i've heard a lot of people saying that a 2003 7.3 Powerstroke is only good for 400 rwhp, what would be a good way to put power to it without things starting to break. Thanks

first welcome to the org.
U will need a set of gauges tranny,boost,pyro
a good chip DP or TS, COLD AIR INTAKE,AND AN EXHAUST SYSTEM, SOME VENDORS WILL HOOK YOU WITH GOOD DEALS

HOPE THIS WILL HELP

I was thinking of the MBRP 4 inch exhaust with possibly the Ford AIS intake, not sure which intake to get. I was wondering about the DP Tuner, even with the 140 hp setting i won't be putting to much power to it, to start breaking things.

[deere4440]

Does anybody have any ideas??

You aint gonna hurt it with the DP 140 if the truck has stock turbo and injectors. WELCOME to the site!!

[deere4440]

Yeah the truck still has stock injectors and turbo, and the trans is still factory

start with this you'll be safe after a torque conv. and a body valve after you can go with tubo upgrade and new injectors and hpop you should be close to 400rwhp

Tranny is the weak link.

I would think that once you get a different turbo, injectors,hpop you should be over 400hp..... with the steup that I have I should have around 315hp or so......
