The SC kit is their stage 2 with rotex c38-91. My question is about boost pressure. My gauge shows good vac at idle and wide open near redline shows around 4psi. Is that normal or is that low ?

I’m the case that is low suggestions why that would be so I can work on it. I have don’t countless hours of searching and reading but the only thing I can figure is changing pully size.

Hope someone can help and thanks

That’s low. Either the belt is slipping so the supercharger isn’t generating boost or the boost is escaping via a boost leak. No supercharger kit for this car would come with a pulley that only makes 4psi.

Or your gauge is broken. Is this an aftermarket in-car boost gauge or are you reading from the ECU?
