He calls it "gas miser" mode.

I assume that mode is still for 91/93 though right? Not 87?

I've never put 87 in it, I wish Arizona had more 93 or ethanol... But you could probably use 87, is not an aggressive map

Got it, thanks.

We just started getting 94 at ALL the Sunocos again.

Unrelated but getting an easy 32 on a mixed business/residential and highway commute. Honestly I think the hybrid turbo improved fuel efficiency (as long as youre not heavy on the throttle)

in general its seems bigger turbos improve gas mileage

Anyone who wants the datapoint, 11.4 mpg, sending it hard at Sonoma raceway. Better than I was expecting - running Dizzy Stage 2.

Probably could have done the whole track day on a tank of gas but it probably would have been near empty at the end, so I filled up after lunch

I get 18.0mpg on average. I’ve seen as low as 17.1, and as high as around 20. Running an E30 tune. Driving the car the way it’s meant to be driven…basically all the time. I always let it warm up for ~15 minutes before getting on it (most important thing you can do for engine health!).

I'm getting around 28-31, mix of hwy commute, neighborhood, and a bit of school run idling.
Haven't done any longer highway runs, and the car is too fun to play with to try to be gentle for a whole tank.

I'm getting around 21-22 running around in LA.

Compared to the 14-16 my wife gets in her Expedition Max, I'm pretty happy with 28.
She does 0% highway to work, and sits in the school run a lot longer than I do.
