MAF Sensor Question

Has anyone ever worked with the differences in the MAF for a Buick 3800 "C" and the
older Buick 3.8L GN or non turbo "3" engine?

I would like to change over to the older MAF if I can for cost and airflow
reasons.  The MAF on the 3800 is the Hitachi MAF, and said to have a different
frequency output than the older MAF.

Is there any repair work that can be done on the MAF's?  Mine gives no fault codes,
but it does seem to be working incorrectly.  My engine has poor power output when
ambient temp is above 60 Degrees F, excellent power around 45 F, and decent when
below 30F.  Temp sensor and O2 have been replaced, MAT has been replaced, and
nothing seems to affect it.

Any ideas on replacing MAF or repairing existing MAF?  Cost of the new MAF is near
$300, the GN MAF is $106.

Has anyone ever turbocharged a 3800?

Thanks!
