That's in the same range that most of us are seeing, Roadking. Only a couple people are reporting bigger numbers and the psi vs inches of mercury gauge scale question never got answered. I had a response elsewhere from a guy who calculated what my turbo boost should be for my HP and displacement and he said my 23-24 psi was right where it should be. Don't know if he was an expert or not, but he seemed to know what he was talking about.

I'd say you are probably OK.
