I just recently installed the package and to be honest I'm don't believe that it even has as much as the edge ez. From a dead stop rpm's run high well past the peak operating range for torque and hp. It takes off pretty well at around 70 and above. I'm not sure that I'd recommend it. Banks cashed my check for over $4300 and I was mo happy with just the edge ez by itself. I have yet to install the brake and tc parts. Does anyone have any advice on possible too much hp and torque for the stock transmission? I was wondering if that built-in trans slip detector is not letting all of the power get to the rear wheels. Does this make since?
