The power, torque and throttle response is simply shattering. Couldn't have asked for more really, particularly with the cost effectiveness of the upgrade. It also seems relatively economical!

I also like the fast and exhilarating and digging the toes in where necessary, or just desired. There's a place for it all. And one can choose how and when. Smooth as silk to... well, nuts.
Sooo fun, and beyond happy.
