OP - I have been flashed with the flex kit for over a month now and for everyday driving 100% E85 is fine. I can say starts took longer and ran a little ruff until the car warmed a bit. Overall I was very happy with the way the car performed until I really started to crank up the boost and timing. Eventually you will hit a wall with the LPFP regardless of it age. It will happen at WOT as you shift from 3rd to 4th around 5000 rpm. This I found to be consistent with 60 to 80% ethanol levels. So, if you haven't already spoke with Shiv or Robbert, order your booster pump and you'll save yourself the embarrassment of coding if you get into a situation in Mexico.
