I wonder if the drag mode is open exhaust or something with an E cut out.
Still wonder how race gas nets 200 HP. Cant see it happening without increasing boost so Im wondering if somehow they can WG it. Or maybe they can open a bypass unless its in mode 3.
The hellcat has a electric throttle body style bypass that dodge used to create the two different power levels in the regilar hellcat. It's not hard to believe they might do the same with the demon.
