Question 2003 7.3 Upgrade

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

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.

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

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......
