Granatelli MAF
but i used it only on dyno and never bought it, you might get some other problems along with HPs gain
do more research, many folks running this MAF, but finally come back to stock one
My 2000 SS didn't get any more power over a stock screened MAF even after adjusting the F/A mixture. I actually lost power (3hp). I tried 3 different GMAF's.
Some cars get gains, some don't.
I know Brandin is trying to sell one in LS1 Western, you might borrow his, or buy it then sell it.
