[QUOTE="SnakeBoostE85, post: 15331893, member: 160175"] Been running 85% to 87% for few years with no issues.... recently I'm finding it harder to find anything but E70 around Colorado Springs. I through the towel in and changed my stoich AFR to 10.62 (71-72%). There are just a lot more stations that have 70-72%, and the last and only one that was carrying 85-87% is out and they don't know when or if they will be getting more. So in doing some calculations, straight E85 is like 105 octane. So if you dilute that with 15% more 86 octane gas, then your at about 102 Octane. Still WAY up there IMO if my calculation is correct. Bottom line - if switching to running E70 vs. E85 should I pull any timing? [/QUOTE]
