I've seen tunes set up two different ways:
1. Timing at 22-23 and A/F ratio at 11.2-11.4, so more timing on a richer mixture
2. Timing at 18-20 and A/F ratio at 11.8, so less timing on a leaner mixture
Why does one choose one way or the other? Does one give more power, is safer....etc.
Is there a rhyme, reason or science behind it?
Thanks
