Hey everyone.

Im still trying to get to the bottom of what is going on with our car.

Im sure that we are getting belt slip but at the same time im wondering now if the gauge is playing up,

We have an AEM Digital gauge installed and when you go on WOT it climbs but jumps around and the higher the boost the more it drops. like 6psi to 2psi, 8 psi to 4 psi etc.

We have installed the small 2" idler pulley between the 75mm idler and the supercharger pulley up top but the problem we are now having it making a belt fit.

Does anyone else have a similar thing happen with their gauge?
