Thanks Mark and Afterburn!
I am going to take the case to the machinist and have them inspect the line bore. The jerks I'm dealing with had the NERVE to take this week off, so I'm stuck waiting

But the car is loaded up with everything and I'll be going by next week. I'll keep you abreast of the results.
What would be the cause of the shuffling?
Someone on the turbo forum suggested it might be lugging the engine. I did have an overly rich midrange that was resulting in lugging conditions. For example if you were cruising on the highway in 4th and wanted to pass someone, you'd give it gas, turbo would begin to spool, AFR's would drop below 10, black smoke, and no boost build up with no acceleration. It did the same when you went to climb a hill. It did this the entire time I owned the car, and who knows how long before I owned it. I fixed the issue with an adjustable wur.
Cheers
Rich
