I have a 2019 Hellcat with Demon injectors, Pulley, exhaust and intake. The car runs perfectly and shows 13.5 to 1 at idle on laptop (VCM scanner) and external wideband. Fuel trims at idle at 1 to 2 percent. 1 to 2 percent at cruise also. Dash AFR shows 12.0. It seems the dash reads about 1 point richer at all times, Even WOT. I am wondering if there is a way to correct this?
Thank you!

No you can't change the way the dash displays. The difference I believe, is because stoich on these cars are 13.85 or something like that and the dash gauge I'm guessing displays on a 14.7 gas scale.
^ Close, it is set to 13.85 stoich so that's what it shows at idle.
If it was set to 13.85 stoich but the gauge was on gasoline scale it would display 14.7 at idle.
The dash seems reflect the tune stoich. I have had people message me and wonder about it displaying in the 9s before when on E85.
