Stock board? Whats the dwell thats too high? I used to run mine at 34 blinks on optimus boards and it ran sweet. Found too low a dwell just caused issues elsewhere. Even though it was more efficient by about 30 shots on a full tank, I had no problem setting the dwell higher for a hassle free game.
Think was dwell 34 BIP 6-12 (summer - winter) and ran sweet for me.
