With my mods I can get 32psi boost. If you get over 40psi then you'll be putting out over 400hp and will need to put in head studs. I would say 35psi gauge would be fine unless you will be going all out in mods. By the way, if they had powerstrokes back in 1196 we should be flying to Pluto by now at warp speed LOL!!

Stock you will probably see 15-18 psi at the most.
6637 Intake, 3" downpipe, free flowing exhaust, maybe up to 20psi.
With my setup in my signature I'm seeing 32psi. Once you get over 35psi you'll start frying the stock turbo.

Some people like them, some don't. I have them and all was good till the other day and I blew my boost pressue line off. I kicked it out of overdrive and got after it a bit to pass a car with the trailer on and it popped off. It just slides on, its tight but still.. It's a poor design. Gauges have been working good otherwise.

I never thought of that glenn. I actually have some of that stuff on the shelf in the shop. I think I'll try that along with a small zip tie for now.
Thanks Glenn

You bet Darin, every tool box should have some, great stuff. I even sealed up a high pressure AC line once good enough to get home to fix it right. When I put it on, I don't mess with it until the next day, it takes awhile to dry all the way through.
