I have a stock 92, just replaced the motor and can't get any more than 8psi from the blower Ive pressurized the whole system with a compressor to 18psi and found and fixed a lot of vacuum leaks but none in the normally pressurized areas of the system. Any suggestions? Also I didn't check the intake assuming that because the vacuum is good it probably is upstream of the manifold. Any advice on where it losing boost would be greatly appreciated
