    Odd, I'm surprised there isn't more info on this, we can't be the only idiots that have run into this lol. Or maybe it's related to re-flashing the ECU strategy from auto to manual? That's the other common thread among our cars, and possibly Kurt's too, who was also having this issue last year.
