It really sounds like a big leak, or something sticking. Check all your vacuum lines too, or stuck diverter valve maybe. The gauge is telling you, either the system cannot hold, or cannot build pressure. I was not paying good attention. Is the car straight again ? the motor can run more boost than stock. And will naturally, with freer flowing mechanical bits. So the tuning will be needed soon i think maybe for those who go over eighteen pounds. Any opinion from the big dogs on this.
