only 12 psi?

I have a 2000 f250 with a 7.3, only mod is a free flowing 4" exhaust.
I put my boost gauge in earlier today, went to the store, and only got 12-13 psi WOT..

Boost leak?

Where did you plumb the line? I have mine in the intake and I'm reading 20 to 25 stock.

And at what RPM are you seeing only 12psi? The engine needs to be spinning good to put up high boost numbers (ain't gonna see it at 1400rpm).

I believe it starts to build boost at around 1800 rpm, but maxes out at 14 psi.

Exactly like it shows in the install link, the 1/4" rubber line coming off the intake to the passenger side.

It built up to 16psi yesterday, and the truck sputtered for just a second.
Felt like when an import hits fuel cut..

Just an unhooked and capped wastegate line.

Sounds like boost leaks. Build a little tool to help you find them. I would almost guarantee you have some, even if thats not the only issue (which it could be).
