I have an LS3 with a Vortech that I'm trying to get tuned on E85. (DSX FF kit and DSX Aux pump) It has already been tuned on 93. Can I modify my current tune so that it knows E85 is in the tank, but not add the additional timing or performance aspects of the tune? Just need to drive it 8 miles to the tuner on E85. No boost of course.
Is that possible? If anyone is willing to help I can upload my tune from my laptop.
Thanks,
