2019 mustang roush stage 3
Hello- I have a 2019 Roush stage 3 with <20k miles (all factory with Roush supercharger). Emissions is showing up as N/A so took to Roush certified dealer and they still can’t figure out the issue.

They did the drive cycle and tapped into ECU and car shows up perfect.

Has anyone else experienced this? If so, any assistance on next steps would be greatly appreciated!
