For what it's worth, mine is in the shop now having the tune tweaked. While they're in there playing around with tables, I asked them if they could turn 4-banger mode back on but only above 65mph. Not sure if it can be set that way (based on speed) but if it can, they'll turn mine back on. I expect bad mileage around town but see no reason not to have it when kicked back with cruise control on.

Picked it up late yesterday and didn't get a chance to hit the open road and test it but the tuner said they were able to enabled 4-banger mode again and set it 65mph. However, he wasn't entirely sure it would work as intended (he'd never tried it on a '17+). Driving home from the shop I was in Sport mode (A8) and did hit the cruise control in 1mph increments from 66mph-70mph. It didn't display 4 cyl mode being activated at any point but that could be due to several factors and doesn't necessarily mean it's not working. I'll update again after I have a chance to hit the open road and can throw it in eco/touring mode on a nice flat road.

I installed an Edlebrock in a buddies C7 and Yes in the tune returned by Edlebrock they will tune out the 4 cylinder mode. So I do not know what supercharger you have but I know Edlebrock will De Tune the 4 cylinder feature.

It didn't sound like it could be tied to a mode....had to be speed and load based I believe. That would be nice though if it only worked in eco mode. Next time I'm in the shop I'll ask/clarify. After more driving though, I can confirm it does not indicate in the dash that it is going into 4 cylinder mode above 65mph like it should be. Tuner has had a hell of a time with the new ECU in these so there may be another table that needs tweaked...
