i'm back to ask another question.
So when i was tuned, using mostly sunoco 93 in the tank, maybe a bit of ultra 94, all "up to 10% ethanol" my a/f was left at 11.7ish. back home when i am racing, using only ultra 94 "with up to 10% ethanol" i have datalogged my a/f at just over 12, sometimes 12.2, but can vary each race from 11.6-12.2 during a sinlge pass, and some passes it stays below 12 on the same night.
basically what i'm asking is should i be worried, or re-tuning for a bit lower of an a/f?
