What percentages? E85 really only shines with higher timing levels and boost, and with 91 I'm sure I was borderline max where it was pulling timing, so after a bit of driving it started to feel more responsive. Once the cable comes in and I can start cataloging fuel trims, timing, knock retard etc it will paint a better picture of where I need to change things, fueling limits etc. I don't want to push the boost though until I can see everything, but it should make quite a bit more if I can get 40% E85 and add a lb or so of boost while not pulling any timing. I have AJ working on a new map for me as well that starts rolling in boost slowly at 2,000 rpm until 3500 where it feeds the rest in, hoping to find a happy medium of traction and torque without making the car just ignite the tires under 65.
