I am taking the car to the dyno on Tuesday and was wondering what you guys think it will put down. It is a 98' WS6 M6 with all the free mods, K&N, MTI cf Lid, Pace descreened 85mm MAF, MAC Y-pipe with Random tech cats, Hooker cat back, MSD wires, NGK 55's, and the stock 10 bolt. The car has 70,000 miles on it. I was hoping for 330rwhp and 340rwtq, but expecting 310/320.

I say put back the stock MAF and you will be close to what you want, 85MAF tend to lean the motor out alittle.

My friend got 340hp to the wheels and that was only with intake and cat back. 02 z28 M6
