I was trying to figure things out, haven't raced in a year. I was leaving at 1,500 and 2,000. It's kinda hard to really load the converter since the car weighs about 3130 with me and gas in it. I read in one of the mopar mags that when racing you want the snubber on the floor and when driving it should be about 1" off the floor. Next time I'm trying to leave without loading the converter and I'll play with the snubber.
