Does anyone here know how to mass emissions with a 21+ FEMTO tune on MHD

Looking to tune my 2021 but want to run MHD and pass MA Smog. I have my stock DP, but wondering how I can pass with the tune without removing it. Anyone here do it?

It will pass with a tune. You're allowed 1 monitor to be not ready. Just depends if your state auto fails for the cat monitor not being ready.

What about the CALID and CVN? Isn’t it auto fail if they don’t match?
