throttle stop huh? i'm using a window switch to take timing out so i'm always running 9.9??. so if i holeshot my competition which is the norm, i run hard to the finish & then look for the competition coming up from behind. i generally guage it so i just get the wheels over the chalk 12" before my opponent.if anyone runs ahead of me i know they'll breakout. with a throttle stop you have to spend more $$ so you can slow it down, whats the point?
