     Well, my two cents:

     Even with different mileage, tune, and ambient conditions...these are
     likely two different engines-all factory ten valve turbos are not
     created equal.

     Ned told me that there was a mid '89 change that increased low and mid
     range torque, and upped hp a bit. It involved higher compression
     pistons (8.4/1 vice 7.8/1), a revised camshaft, a smaller turbo for
     faster spoolup and less turbo lag, a new intercooler, and two (instead
     of one) knock sensors.

     I routinely see 1.4 bar, i.e., when I routinely stand on it in
     third or fourth gear, engine warm, above 3000 RPM. This seems to
     be normal for these later 10 valve engines...
