XCal 2 with E85?
I know quite a few guys on here have the XCal 2 tuners, but I was wondering if anyone uses them with E85? I am also wondering what kind of mileage gains you may have gotten with it. I run E85 and want to see if it will change any of the numbers I could see mileage wise. I don't want to shell out $400 if it won't help me in any way at all. Any response is appreciated.
