I got 10 psi with my guage on my intake hat.....after my intercooler and 10 feet of piping. My turbo must be around 16-18 psi.

Hey Dirty, what kind of performance increase did you experience with this?

Seems a tad much.. I would expect a 1-3psi drop.

Do you still have the original factory muffler on? if so it is most likely so clogged with soot that you cant get the exhaust flowing fast enough to spin the turbo at a rate that will build boost any higher. When I first got my truck and put a turbo on it, I couldn't get above 5 psi boost , then I got a wild hair to upgrade teh exhaust. When i pulled the muffler , it was so clogged and heavy that I couldn't lift the thing . A 4"system with a straight through big truck muffler later and it would do whatever I wanted it to ( I've currently got it cut back to where it won't go much over 8-10 psi though, I tow heavy and I dont' like to have to just sit there glued to the gauges )

Thank you very much for the reply 94. Its a brand new $60 Phantom AutoMeter gauge. And Fidy Diesel and I have seen the difference in boost due to the mods we have done to her. So I know the gauge is good.
