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.
