It was on 98, e85 i find is a lot harder to crackle but i believe we left it at 5deg on decel from 2-3k, didnt even try doing it waves as he was very happy with it
i had to run -15 deg to get some sort of pop on e85 but then it drove weird as i think the quick jump from going to -15 to +25 on accel made it feel funny
