I just got my swap done and drove it today. Its only boosting to 6-7 max psi. I think the mechanical boost gauge is ok because its vacuum is reading 20 at idle. When I pinch off the vacuum hose on the side of the turbo the boost goes through the roof until fuel cut! Is this normal for a stock 1991 st185 with top mount intercooler to only get 6-7 psi? I thought it should be about 10-12 psi. Or is that psi only possible with modifications to the wastegate? Thanks for the help!

6-7 psi should be running off the wastegate only...the boost controller sounds like its not doing its job
