like I said, big cost for getting rid of throttle lag, which some people wouldn't even notice, but if you want the best performance, you will like the difference it makes...and yes, you can make up for throttle lag while at the track with a little brake torgue, but I like it all the time without having to do that...besides, I would just spend the money on the Harley...the car should get its share from time to time...
