I’m new to forums in general and would love if someone can help me figure a few questions out. If not please send me in the right direction. I bought a 2011 370z 6mt has a GMT supercharger kits along with all supporting mods.

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
