Stock Turbo Max Boost?

2000 F-350

Hypertech stage 3 tuner (out dated but works great)
6637 intake
straight piped

Im only making 21 pounds of boost, is this normal for a stock turbo? Is there ways to pound more boost out of it?

You need a boost cooler to tell the computer to stop defusing. Also, a better set of tunes will work wonders. I saw 26 with tony wildman tunes.

The stock turbo will only make about 27psi max. This is further limited to 21psi by the PCM. Get a REAL tuner (or boost fooler if you are cheap) and you can get that last 6psi.

On a consolation note, the turbo will make more, but you need more fuel. I spooled 34 psi on stage 2s on a stock charger.

On that note. If I start adding boost and later in the future I get a larger turbo, injectors, ect.... will i need to install head studs? How much abuse can these 7.3's take before a guy should install studs?

Most of the guys I run with are pushin commins and im a diehard ford guy, This is my first stroker and I dont wanna take advice from them..

Hypertech is junk. Beans or Tony Wildman. Make sure to get a tow-tune.

Head studs, 40psi+. Not typically a big deal on these trucks.
And whatever you do, dont listen to the Cummers.

I'd look at TW, gearhead or beans for tuning. Don't worry about headstuds unless you are pushing some power and see 40psi often. I'm running 250s and I don't have headstuds yet. A good tuner will manage cylinder pressure so you don't have to worry about blowing hgs.
