So let me get this straight. You use 93 octane fuel and run 9 degrees of timing? WoW Thats pretty harsh man, and there no point to doing it. If you wanna gain power you advance timing and upgrade octane. On 87 octane I'd go no higher than 5 degrees advanced from the stock 10 degrees. Theres been a lot of issues on octane lately and most people think that higher is better but its the exact opposite. No wondering your engine was doing that. So try 87 and 5 degrees advanced or just before it starts pinging(bb's on a tin roof). Let us know how that works out!
