It's WAS 2.7, and as far as settings, all I know is that dwell is at 6.7 and debounce is at 2. I'm thinking about just buying the Hybrid ram cap with a bumper in it, would that be a good choice? Meanwhile, the bumper that I have is almost worn down, and I was wondering how to get it out of the ram? Once a new bumper is in, is there any adjustment necessesary?
