I set it at 6 degree initial and 22 total with vacuum advance disconnected. Seems to have good power very little pinging on initial wot. It is a little bit worse at 9 degree initial and quite a bit worse at 12 degrees inital. My distributor is giving me 16 degrees mechanical advance.

Don't know what else I can do with out adding 110 octane. Right now it is very drivable on 93 octane just not sure how the 22 degree timing will effect it.
