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!

im having the same issues with my swap, but once mine runs for about ten minutes it leaves safe mode. you should put in the Knock lights in the FI stickies. they have helped me narrow things down a bit. I haven't heard the restrictive exhaust one, but that sounds legit, because my car wasn't in safe mode when i had the stock exhaust unbolted.
I also agree with Art on the TMIC, mine is burning hot after driving... which means it isn't helping cool any!  keep us updated
