    I used the "Button" for several years running street stocks. There was a learning curv. First on how to bump start the car and shift without a clutch. Figured that out on the street in front of the shop! Then I had to re-learn how to drive the car off the corners. Amazing how much extra torque the car had from 1 week to the next. It really woke up and turned the car from a mid pack car to a contender.
