It is a system like Al, but we have different tuning. I never got a chance to keep jetting up because my clutch went south during the initial tuning. We were going to let the new clutch break in before increasing the shot on the second time around, but the valve spring broke during a NA run. All I am going to say is I was very close to Al's #'s when my clutch gave out. Testing will resume once I decide on what the new motor is going to be.
