what is the best afr for a stock ls1 ok i have already tuned my stock internals, full bolt on ls1 without torque converter. the best i got on the track was 12.68@109. im currently running 13.3 afr lowend and 12.8 afr on the topend. i read that 12.8 was the best power for ls1. then i also heard that 12.2 is best. what do you all think.

But you're a little lean. Try going from 12.9-13 low end and 12.2-12.6 top end.
If you enrich the mixture a little you can give it more timing and it will make more power.
What are you using to tune/log?

im using Hp tuners with lc1 wideband. ill have to try it on the track to compare. right now im running 26 timing but i knock so it lowers it about 2 to 3 points. another friend of mine told me to go richer and put more timing so ill give it a shot. thanks
