Speedometer correction due to tire size change
I've been considering increasing wheel size by an inch on the front and back. I know with my mustangs, I was able to recalibrate the speedo using a handheld tuner. Is there a way on a 2022 C8 to correct the speedo after changing the wheel size? TIA

The only company that has broken into the C8 computer for tuning at this point is Trifecta, and they don't do hand-helds or individual tunes (they are focussed on doing 3rd party for things like blower kits from what I've heard). Both FuelTech and Pietz (Delta Control) have piggyback tuners available, but I don't think I've seen anything on either of them to allow tire size change (plus it would be a really expensive way even if it did). So at present, there's no way to correct the speedo for different tire sizes.
What most people do when increasing wheels size, is to run a lower profile tire with the same overall diameter as stock, which won't cause the speedo to be off.
