Thanks again, Glen

Glenn, assuming your boost gauge is working properly, you might want to check for any exhaust leaks ahead of the turbo. Cracked headers are common with these cars, and often don't show themselves ( noise wise ) @ idle. Look at all weld joints where the primaries meet the main log. I like to start the engine cold and quickly feel around these areas for exhaust pressure. If everything is fine, you should look at the wastegate. The spring could be weak from age, or the diaphram could be torn and not be keeping proper pressure on the wastegate puck. Then there is the boost solenoid ect--------but start with exhaust leaks first. Brian
