Over the winter I switched to e85 had carb professionaly built runs great did right out of box but I've got a consistency issue the slightest change in air the car changes numbers rapidly yesterday at track ran 2 different full races yesterday made 9 passes air temps between 73-79 humidity between 42-56% car ran all over the place from 7.61 to 7.70 where I was watching every one around me running dead on a couple lost 1 number when night air got good but all in all dead on that's part of the reason I switched to e85 was the dead on consistency with everyone around me I watched was dead on all time no matter the weather unless it was a major change in temp/air and I do mean major ....I lost race because of the inconsistency issue what I'm trying to figure out is do I tune it like gas and start dropping jets 1 at a time until it gets right?running same combo as last year that ran pretty darn consistent for gas it would've dropped 1 number in the changes yesterday ....any opinions I've been checking plugs regularly they look good a little rich at idle but overall good
