I say go full Kramer and see how far you can go on empty.

 

Check your SOC via FORScan.

 

Bump the SOC to 95 with Forscan. I think it's set to 80 stock.

 

80% is where it should be.

 

I have a 2017 and just replaced the battery last summer. What I noticed was that some of my settings were changing after start up (example - reverted display to tranny temp instead of turbo). Battery test showed it was down to a couple of hundred cranking amps, should be 6 to 8 hundred. I suspect the voltage sag at startup was impacting the electronics. New battery and the "magic" stopped happening, plus A.S.S. is definitely more aggressive when I forget to turn it off.
