Anyone calibrate speedo while running EFI Live?

[mjsmallz]

I have a 2019 Ram 2500 that is running EFI Live and I just installed a 6" BDS lift with 37's. Just wondering what people are using because I am leery of getting the dealer to do it. It's about 5mph off right now.

I used AEV ProCal Snap, was able to change tire size and pressure.

Most dealers wont change that anyway - most people use alphaobd. Im not as familiar with EFI Live but other tuners like EZ lynk allow you to change tire size for speedo.
