Re: tuning my self ...
I like 12.5:1.
Careful with timing, as you can wreck stuff by running too much without ever seeing knock. Cylinder pressure skyrockets with too much timing. You need to tune for power not knock. My knock sensor became totally useless once I switched to E85 4-5 years ago; 1G's are a little different since the knock sensing system is over sensitive IMO.
