"My only complaint is there are no specific instructions for installing the device in the vehicle. Not everyone has Ph D. in auto mechanics and I had to do the installation twice per a intallation procedure step which was critical to the proper function of the product.
As for the product itself I have seen a distinct improvement in the transmission shift pattern and a small increase in the overall performance of my car. I think more modifications need to be applied to get the real benefits of this product.
This product should be marketed with a much lesser price in conjuction with the accompanying complimentary performance parts." —James T from Greensburg, PA bought a Jet Performance Module for a 1999 Ford Crown Victoria, 4.6L V8.
