So I just picked up my 2012 GT and I was curious about E85 for the track. My issue is what do I need to run E85 at the track on my 5.0? I know I need a tune but do I need bigger fuel injectors, newer spark plugs, a new fuel pump or anything? Also after I am done at the track and go to drive the 50-60 miles home can I mix 93 octance E10 in with the E85 to get home?
