I'm sirouse, I am the only guy in the States that has this. This has been in the Europ and Japan for more than 4 years. The factroy softwear limmits the performance of the electric motor. Just for everybodys infomantion, electric motor puts out about 285lbs of tourqe. So this softwear puts the electric motor to use the way it's suppose to. The factory softwear works mostly gas some electrical. This program works mostley on electric and some gas. Think about it and its possible but not passible becase gasoline industry has big power and it's a big bussines.
