Racechip ultimate for n63tu with e85

[doggboy]

Hello gents, i am hoping one of you can point me in the direction of the info i am looking for. I got a screeming deal on a racechips ultimate piggyback, and reading around it seems like setting C is what people preferred. I couldnt find anyone who ran 30% e85 on it though. I will try the e85 either way since i am stuck with 91 octane here in Kalifornistan, but i was looking for anyone else who may have turned up the racechip, or had found a better e85 ratio.

I wont be hitting a dyno, so i am hoping someone has alrwady done the leg work for me!
