Stock MAF, you're going to need more mods before you see any gains from a bigger MAF. Also there is no need to buy a Granatelli 85mm MAF ever, a 85mm Delphi truck or C5Z MAF would be just as good if not better and would be cheaper.

If you are going to do anything use a 85mm truck maf. I bought a Granatelli, it didn't give any better results and the car wouldn't pass emissions. Put the stock one back and the car was fine. My friend wanted it so I gave it to him and it was the same thing. Car won't pass emissions, Also Tuners hate them.

Thx guys for the heads up I saw it on Craigslist. The engine is going into a 81 malibu. I didn't get one when I purchased my ls6 intake
