Big Gun Rev Box

Has anyone run the Big Gun Rev Box on their 650? And how did it perform?

Is this the 650R or 650L we are talking about? Either way i believe the only benefit would be if you were to throw in a high comp piston to make use of the higher limiter.

Some people use the XR400R CDI i believe?
