Just to let you guys know I talked to Granatelli Motorsports today and they told me to call their sister company in MI. Anyway to make a long story short they have what they call a bosch drive for a Ford MAF. The drive itself is $150.00.

is the ford MAF supposed to be that much better than the mods you can make to the GM unit?

'87 Monte Carlo SS,with '89 IROC 350,700 trans, blew up 3.73 posi stuck with crappy 2.73's neeed gears! hooker headers, flowmaster 2 1/2" exhaust true dualls, recently installed a set of alum vette heads 58cc, new cam for a paxton, recently installed paxton, OMG need a posi bad. So if anyone knows where a buick GN 8.5" rear is let me know.

The ford units come in huge sizes compared to the GM units, they flow much more air for very serious engine setups. The big problem is still that the ECM is limited to 255gm sec of airflow, that's the biggest problem some are working to solve. If we dont get a fix for the 255gm soon I will be a speed density convert myself.
