So ive been looking all over Google and can't find what I'm looking for. I just finished with my first 100 miles of dizzys stage 2 93 tune and im pretty happy with it. Def feels like more power and way better throttle response. Now I'm ready to put some e85 in. My question is when after I put 3 gal of e85 in do I actually switch the tune? Immediately? Wait a few miles of driving then pull over and switch?
