turbo psi

on my 2005 6.0 I am questioning my turbo psi. When I stomp on it I cannot get the boost above 20 psi. Is it possible I have a leak somewhere? or is this reading normal?

You definitely have a leak. Check all of the blue intercooler connecting boots. One has either come off partially or it has a tear in it thus letting out most of the air pressure.

Yes, you could also use a small mirror to inspect the sides you can't see. Sometimes they can rip right at the clamp wear it's hard to detect, might have to remove the boot to inspect it. The one coming off the turbo (45*) is a common issue.

+1

Also check the Y-pipe and up-pipe on the back side of the turbo.

Is there a torque spec for the clamps on the blue hose. I was just going to buy new hoses and see what happend but then I saw they were $200 for hoses and clamps so maybe I will do a little more digging first

I got an 06 F350 Crew cab dually a couple weeks ago and after reading this thread figured I would check my turbo boost. The first time at WOT the turbo boost gauge read 22. I done this 3 more times at WOT and it reached 27. Kept getting better each time I got on it.
