Yea all the 2020 Models need the ECU patched.

Woah. Bootmod3 is available for the 2020/2021 models?? Nice! I don't even see it on the bootmod3 website. What does the ECU patch entail? How do you go about doing that? My 2021 is on its way and I plan on doing a tune and exhaust once I am done with the break in period.
