I am very happy with the numbers. This is the same dyno that I have named the "heart breaker". This cobo runs amazing. You can let the clutch out in 1st with no gas and there is no bucking what so ever. It literally drives like stock. We also put in cut outs after the dyno so don't know how those would have effected the numbers.
