I dyno tested a M3 fuel cone on my almost stock 91.5. The only mod was the fuel screw turned in to the collar. Ended up getting 50 hp and 82 tq from it. The operator left the parking brake on during all those runs which is why the numbers are low. He gave me a few free runs when he realized it and I finished with 193/388.

Sweet i just installed my m3 pin and it was an improvment over a bully dog pin even. I am satisfied.
