<O> Well, my two cents:
<O> Even with different mileage, tune, and ambient conditions...these are
<O> likely two different engines-all factory ten valve turbos are not
<O> created equal.
<O> Ned told me that there was a mid '89 change that increased low and mid
<O> range torque, and upped hp a bit. It involved higher compression
<O> pistons (8.4/1 vice 7.8/1), a revised camshaft, a smaller turbo for
<O> faster spoolup and less turbo lag, a new intercooler, and two (instead
<O> of one) knock sensors.
<O> I routinely see 1.4 bar, i.e., when I routinely stand on it in
<O> third or fourth gear, engine warm, above 3000 RPM. This seems to
<O> be normal for these later 10 valve engines...

Well FWIW I often see 1.4 bar & I have a 1988 10V turbo motor.
Could just be calibration variations in the boost guage.
