I have a 1990 xr7. It's all stock. What should the boost gauge rear at WOT? Mine is reading 7-8psi. I was thinking it should be like 10-12psi.

yeah around 10 but those stock boost gauges aren't accurate

Ok, I was thinking I might have a boost/vacuum leak. It stays at 1500rpm for about 10 seconds and drop to maybe 1100 and won't idle down any lower.
