My flex sensor showed 79% Ethanol. Prior to the pump install I would code after shifting to 4th at WOT. So after install I was launching in 3rd at the event and pulling through 3rd, 4th, and 5th trapping between 150 to 160 depending on traction and cross wind. So regardless of what tune you run, the pump will allow you to run 100% as long as you address the fuel trim issues with the DME.
