Tire size calibrator: what are you guys using

[My_first_RAM]

I am about to go from 33s to 35s and looking at calibration options. On my jeep I used the flashcal and I wanted to get some recommendations. Let me know what you guys are using and what additional options are out there…anything beneficial outside of calibrating tire size.
Thanks.

AlfaOBD

I used tazerDT just because I got a good deal on a used one. If I were paying full price and/or only cared about changing factory configurations, I’d do alfaOBD before buying a tazer.
