I've not done a track day or out to justify anything like this as in reality its not much use to me but at that sort of price I could see my self buying one as a kind of gadget for the car and to light up on my little blasts out and about now and then.

Does the programmable shift RPM also limit the engine RPM and will it work in conjunction with a re-map ie Dreamscience?

Seems like a great idea to me.
