I don't really like it. Well, let me be clear. I used a Vitesse Throttle Controller, which in essence is the same thing. I found that it did give the throttle a small amount of "sharpness", which I think some will perceive as taking away some of the lag that all throttles, cable or our electronic, inherently have. There is absolutely no power to be gained here, so just be clear what you're getting. The other issue I had, and many, many shared the same issue on the Camaro and Corvette forums, is we developed a CEL for the throttle position sensor, and it was only remedied by disconnecting the controller.

I won't be buying it for my 4Runner, and would rather spend the $$$ on a better intake or exhaust, but knowing that neither of those will fix the lack of power our motors have. I didn't buy it to race, so I don't care.

Not trying to rain on anyone's Sprint Booster parade, but when I read your quote, I felt the need to share.
