Even though mine isn't a daily, 98 is for me, also my boss pays for it I have seen these flex tunes, does it run 100℅ on either, or is it like the old gas tunes where it runs better on one? Does the tank need to be nearly empty to swap between them? I will never run bigger then -5s even -7s would make me chub up enough. I have a mate with an SS on OEM e85, too little servos, it just seems inconvenient to me....unless its a dyno queen. But that's a whole different gear grinding story lol
