Progressive timing retard
What I'm thinking is that if you have a 250+ shot progressive, and set the timing according to that, wouldn't it be too much at the start and possibly create a bigger chance to backfire? I know they staged timing controllers but do the have progressive?
As far as the the timming with the 250 shot. You can set the car for the set timming needed with that size shot and you will be fine.
