my question is, when I punch the gas I only get turbo psi up to about 10psi, then stops, before if I'd have turbo psi up to 20psi + any ideas, it's a 07 f250 with no work done, it has 154k

Reason: More info
Most likely will need to clean and or replace the turbo I had cleaned mine 6 years ago for the same kinda issue and just this summer the unison ring seized up again. I just bought a new turbo this time around
Ok I just checked the hoses and boots, and the black plastic pipe, cold side into the elbow had alot of old oil on it, cleaned it up and checked, no cracks or holes in any of the boots or piping
It will only build boost to 10psi, after that the rpm will shoot through the roof, until I back out of it, and there are no codes coming up, even after I punch it and the turbo stops at 10psi, and rpm shoot up
Remove the MAP hose from the manifold and check for any
goo in the fitting that threads into the manifold and then gently
remove the hose from the sensor and check it.
