Installed mine on saturday and like everybody else says, the install was very simple, the washer is the toughest part you definitely need a magnet to remove. After the install took I went out for a little cruise and was very impressed with the increase in the throttle response and pick up from a stand still or from slower speeds. I went out on the interstate to see the difference at higher speeds and when I pushed the pedal to the floor the engine shut off. Pulling off to the shoulder I turned the key off and then started the engine and it started right up. Took off one time and when I pushed the pedal all the way to the floor again the engine turned off. Started the engine, it started right up and then drove back to the house. It seems that when I push the pedal to the floor and hits the switch at the bottom of the accelerator it shuts the engine down. Has anyone with an auto-trans had this problem after their install of the sprint booster? I've never had this problem before but I will uninstall the sprint booster today and drive without it just to make sure thats what the problem is. Could I have possibly gotten one for a manual and I have an auto? What's the part # for the auto?
