Bring Dyno mode back

[drag_racer]

or at least make the ESP off stay on for more than the current key cycle.

I loved it with dyno mode on at the track (and no, I never went into limp mode ever), but now with the new crom for the gas mileage tune, dyno mode is no longer there.

It would be nice to have dyno mode, so that I don't have to keep plugging the predator in before each run at the track to turn off ESP. Dyno mode did make a bit of a difference at the track


And for those that are wondering, mine is a early build '05 Magnum R/T AWD. None of the ESP mods work except for cutting the power to the accelerometer underneath the console.
