I have a Garrett GTP38R Turbo and i know its capable of 40 lbs of boost but I'm having real issues getting my psi over 25. On a rare occasion i can hit 39 lbs. I have cranked the rod as much as i could and have even used shop air to push it over with no additional boost..... Any thoughts to pull out some higher numbers?

Do you have a boost fooler for the MAP sensor? If the boost gets to 25 psi, the PCM will defuel to keep the boost down. You need an ITP diesel boost anihilator.

I have a Airline restrictor gauge in it from an air compressor and the map sensor does not read any higher than 24psi.... You figure an ITP Boost fooler will work better?
