Sprint Booster
Finally got the Sprint Booster installed. What a difference in throttle response. The car goes...immediately.
One thing I learned was to let the car sit for 10 minutes with the door open. Keep the key away from the car for that period of time. I left the key in the house in a remote area so the key and the car could not communicate. The car needs to be totally asleep.
Install the SB by removing the pedal. A 13mm socket is needed. Unhook the OEM plug, install the SB and reattach the OEM plug. It just snaps in. During this installation, do not press on the brake or throttle pedal.
Once installed, turn on the key to the first detent. Do not start the car.
Also do not depress the brake or throttle. Let the car sit for two minutes with the key on.
After that, start the car and let it idle for two minutes. You should be good to go. You will notice the difference right away.
