I recently bought this off Brian Franchi, thanks for all the help man. And I cant say enough of how much I love it. Its so much more than you'd expect. Yeah I expected better throttle response and I got it but i also get the really cool performance tests an gauges it offers for various vehicles. Everything on it is customizable from the color of the screen to the gauges you want to run. I Definitely think it was worth my 600$.
