Ok so just installed my jrsc. Everything seems to be hooked up right. Problem, idle likes to go up down up down up down in about 100rpm increments. Also, when I rev up, and the revs fall back down, it stalls out. Vacuum leak? Fuel? Timing? First supercharger. Btw my mods are Jr 4-2-1 headers, test pipe, 2.75" all the way. Maybe bad charger?

Talked with Gary. He made some good points. But I did find my issue. If anyone has this kit, and your setup starts moaning extremely loud, it's the bypass valve. Mine failed on me. There is zero movement coming from it and it is stuck in boost position. So no matter what, I am boosting. Bad time.
I had that happen on the EMod car. The vacuum line was hooked to the wrong port and forced the recirculating valve closed all the time. It made for some awesome full boost gear shifts.
Which line exactly? Any way of pictures?
It was an MP62 off an Xterra on a Nissan KA24de motor.
