Getting 7 MPG while in ERDTT...

Seems a little low.

You would figure the engine wouldn't run so rich while cold (30 degrees F) - (more fuel = lower combustion temperatures). Only drive one or two miles in ERDTT (for about 5 minutes) but, what a hit to MPG.

I'm thinking the gas "guess-O-meter" may be off and needs to recalibrate.

Instant MPG is misleading for any vehicle. It could hit 99mpg if going downhill on most ICE cars.

For perspective: At full power, a 700HP Hellcat uses a tank of fuel in 20 minutes.
