My LT1 has 33 degrees at wot. I'm running about a 115rwhp shot with TR6s and 93 octane. Looking for opinions on how much timing to pull with the 685 box. Thanks

Isn't it like 2 degrees for every 50? If so, that would be safely 5 degrees right?

I guess, but some with stock timing hardly pull any, and some with less than a 100 shot have pulled none. I'm not saying it's smart, just looking for opinions. Thanks

Maybe one or two degrees. Not that big of an issue until over 150 shot in my opinion. Need to watch for knock/detonation. The high end of timing that det. is controlled and a safe afr (11.8 - 12.4) is a good start. My experience has been my stock tune ran ok with 100 shot. I will go to 150 soon so it will need a total review on timing, afr etc........

Having the right safety systems is important. They can absorb some of your mistakes.

Good luck.
