Thought I'd let you know I also joined the E85 club today. I loaded the Jon Lund E85 tune. The car is running smoother overall than with my previous Bama 93 race tune, but definitely roasts the tires through the first three gears. My next step is to datalog before anything else but my job will keep me from doing that for about 10 days.
I'm not planning on a dyno session, but will get back to the track when the weather cools off (probably somewhere around the beginning of October).
