I just picked up a Gen III and the turbos are only producing 3-5lbs boost and at times not spooling at all. I had them looked at by a rotary mechanic and he told me he couldn't figure out what the problem was but that he replaced the grounds (that's what got them to 3-5lbs, they weren't spooling prior to that - the car didn't have a boost gauge and when I drove I'm positive I could hear them spool and hear them blow out plus feel the boost, I bought the car 3 days later without driving it again) but he said they were probably "just tired". What does that mean? Do I need to give them some gatorade and a power bar? What do you guys think? Replace them or is their work that can be done to them?

sounds like something in the rats nest, or possibly clogged pre-cat, as that is normally the first to go. What "rotary mechanic" did you take it to? List mods to the car, mileage. etc. and we can help more...
