I think my haynes manual said the turbo should be around 145, with anything less than 100 psi needing a rebuild. My engine, with 100k+ on the engine had from about 130 to not quite 140 psi. Not too bad, I guess. Also, make sure all cylinders are within about 10% of one another. One really low cylinder means you need a rebuild.
