Picked it up this saturday with E76 in the tank, it made 496 with 424 tq on that mix, drove it up to nyc on 95 and filled up with 93, mix was E26 at that point and the car didn't miss a beat, AFRs were right on track and had great power and spool soon as i pulled away from gas station. Used the fuel pump cycle feature (holding down cancel on wheel turns on fuel pump) to get the mix to stabilize before leaving the station and going in to boost. Car runs and feels great, no more jugs of E85 and range anxiety!!

 

Awesome flex fuel setup. Makes me excited to get my EF2 setup going.
