If possible, do a boost leak test. It's amazing the problems leaks can cause and how common, but unrecognized, they are. Here are a couple of links on building testers: http://www.srtforums.com/forums/showthread.php?t=195139 http://forums.beyond.ca/showthread/t-87413.html You don't mention any unusual noises. When I got my '89 CSX, it was building boost very slowly (and it's a VNT!). It turned out that there was a bolt missing between the turbo center section and turbine housing. The hole went straight through into the exhaust stream, so it was a huge exhaust leak. Sounded like a truck when you got on the accelerator, though, so I knew there was an exhaust leak.
