MAF kit and tuning, Split Second
 

FYI

Split Second makes some interesting products that migh be worth looking at for our 3.2 and newer cars.

They have a MAF kit that is designed to work with Motronics. There is an interface controller that seems to have a simple method to effect tuning.

See: http://www.splitsec.com/index.html

They also have interface controllers that take control of fuel and ingnition and add a manifold absolute pressure sensor that should make turbo instillations easer.
