Anyone have experience with E85 conversion on NA 2015+ Mustang GT?

I have ran daily for a few miles and love the E-85 had them balanced and they reel great!

Long overdue update. Sorry. Thanks for everyone's help. I have now driven a full oil change on my current E85 setup, and I am loving it. I ended up not going with a flex fuel tune, went with a straight E85 tune (and another straight 93 octane tune) from Blankenship Tuning. Figured that would be the best option to get the most performance considering I did the GT350 IM swap at the same time. Car runs like a rocket, and I have no quams about revving well into the 7000+ rpm range. Havent been on the track yet, but, red light to red light around town, I haven't found any NA cars that have given me any problems!

Video is needed! What are you shifting at?

we got ballsie on the dyno and ran it all the way up to 7600rpm. It was still holding 426hp and 393tq at that rpm. That was a little scary for me tho! I have my shift light set at 7300. I feel comfortable there.

I have some build pics and some run videos. I can post them as soon as I figure out how. Im not very Forum savvy.

yeah 47 lb injectors stock fuel pump , and 93 octane here with stage 3 cams gt-350 intake and tb and more....

Thank for starting this thread but what are the hp gains when going to E85 on a N/A setup?

10-15 is what I've been told. Ran E85 and full exhaust on my 16 and it felt pretty quick. Never got to a dyno before I got rid of it though

which 47lb injectors were used when upgrading. I cant find which ones to buy the ev6 or ev14

I am not sure what HP gains I got from just the E85, but with the tune/E85/GT350 intake swap I ended up with 423/374 at the wheel on a Mustang Dyno.

My buddy with the exact same setup minus the GT350 intake, ended up with 416

Why is it these vendors haven't figured out a way to incorporate a true ethanol content sensor with these flex tunes? I don't like relying on the O2s for econtent % changes. Hijack a useless ECU input and run a GM 5v sensor to this input. Then write the code / tables in the ECU for the reading.
