You can't run much boost with the clutching you have. That's the first thing you need to address before you start adding boost. Justin would be able to tell you. I don't know if you could get away with 8 or 10 lbs. If you're gonna be running much boost, throw at least a couple of gallons of race fuel in each tank to help spike the 93 octane stuff. You never know what kind of fuel you are getting from a gas station. If you think race fuel is expensive, start replacing cylinders and pistons 4 at a time...
