Are we talking the 3800 or the 3.8L?

The Grand National used ECM #1227148.

Standard GM 2-Bar MAP sensor (15PSI Boost)

I'm not sure of air flow spec. for this sensor but it cannot measure the
airflow past about 250HP.

Why not just use an entire engine assy. from a GN or T-Type Regal? The block
and crank are stronger and the assembly is not too expensive. Not to mention
the fact that aftermarket parts for the turbo V-6 are plentiful, inexpensive
and work well.

Just my .02...
