There's a guy I know who runs an ATI Pro Charger and I believe he's running stock ported heads and the rest stock. He's getting 14lbs of boost on pump gas. I think if I was going with a supercharger I'd have to go with an ATI. A buddy (stangsrule) has a Kenne Bell and has had lots of problems dealing with Kenne Bell on the chip and such.
