So I'm trying to figure out how much total timing i can safely run. I have a bolt on gt and have a 93 octane tune from delta force. I then added 3* onto that tune, and at wot I'm at about 33.5* is the highest i reach. My afr's are about 12.4-12.6 which i'm good with. Just need help on the timing, i searched and got everything from 26-40*
