The car loves it and runes even smoother. Try that map out first with the mix, then see how you like it. I'm just finishing up my 93 octane protune now with PTF, then I'm gonna get the e85 tune to run about 40% e85. It'll definitely put you over your 400whp mark. Just make sure you can get e85 around you before you get your hopes up. I have all the same mods as you do, so don't worry about it.
