Ok so i just got my car back from the dealer just got my stage to done! Everything is good the car pull's alot better and harder,but before i went and got it done i was only boosting 10psi @6400 rpm thought it could be do to where i live less air,But now that i got the stage2 done im only boosting 13psi@7000 rpm. I think it is my stock gauge is there anything i can do to check it out my self other then check for leaks and stuff cause i already have???

 

it's probably your altitude depending on where you are in colorado. the higher up you are, the less it will be.

 

nope. its fine. stage 2 is about a 3 psi increase. and at your altitude, you will be boosting less than most of us.
