I'm actually testing that right now. I'm running the gear advanced 1 tooth which is 5* as there are 72 teeth. I'm just curious if it would be better to run more mechanical advance and no timing box, and retain the dynamic timing, or run some mechanical advance with a timing box.

So far, no codes with mechanical advance, and it runs great on the street. I would like to get on a dyno soon and do some back to back testing, with it advanced vs. not advanced, and I also intend to run back to back at the drag strip this spring when it opens back up. Like I said, on the street it seems great. Even with a hotrod pump, I'm running lower EGT's and less smoke than I was with my SO vp.
