Hey I have a 93 cummins with a stock turbo on it with a new fuel pin from PDR, 3200 spring, the pump just barely turned up(plan to really turn it up when I get new injectors), and I have a cone air filter on it (you can really hear it whistle). I just put my boost gauge in and i can barely hit 10 psi this is pedal on the floor. From the research I have done this seems low. I made a boost leak tester and I couldn't find any leaks but did notice that the turbo was leaking some oil into the pipes so I was wondering if the turbo is on its last leg? Any one have some input. Thanks.
