Hey man..I really like it and it does make a dfference. I have the switch located on the side of the console. When I have the unit off and on a highway, I toggle between Sport and Racing and you can feel the car surge forward and perform better...not faster...just more responsive. Keep in mind I have an Auto Trans.
You should be able to obtain a discount code..which should save you about $50. Check around.
