Can you tell if you are getting in discharge air out of the supercharger?
Do you have a compressor bypass valve installed? If so it may not be working right or installed incorrectly.
No valve installed. And there was discharge air comming out of the unit when I spun the head unit before install.
On the Auto X-ray, I was showing a pressure of 1.4 lbs. Yet nothing on the timing retard or the gauge. It does go up, --shows less vac. -- yet not into boost when you hit the throttle and get the RPM's up and running.
