My car is at SP right now, and they've been doing a tune on it but can't get my turbo to boost over 18psi. I have an EBC Profec B on there and they said that even cranked all the way on hi boost 18 is all they can get. It's 67 turbo so it should be good for 30-35psi to my understanding, and help? Could it maybe be the EBC? They fixed all the boost leaks too.

Sounds like it's not hooked up right, or the Profec could be faulty, maybe the solenoid valve isn't working properly?

how many psi is the spring in the wastegate rated for, if its a 67mm i doubt its building enough pressure in the exhaust manifold to force open the wastegat, but if you only have a 6psi spring i guess it could do it.

It's got a 14psi spring in the wastegate and the turbo and wastegate are both brand new.
