MAF

[David A. Cooley]

Thomas,
The MAF is indeed a freq. generator.  After looking at my 95 LeSabre Series
I 3800, a bigger MAF isn't necessary and may cause driveability problems...
 I have my exhaust opened up to 2 1/2" dia and a gutted cat, no resonator
and a Walker Ultra-Flow.  At 5300 RPM and WOT in 1st gear, my MAF only
registers 170Gm/Sec airflow... 255 would be max for the unit.  If you were
to go with a bigger MAF, you'd require a re-write of your MAF tables
(Assuming it didn't measure the same exact freq per reading) to make it run
right.
For a turbocharger, contact Dave Buckshaw at EFIPERFORM at aol.com.
Later,
Dave
