N52 3sim stock tune for ca smog

Anyone have any issues having their car smogged with a 3sim tune in California? How simple is it to flash back to stock? I had a mhd tuned 335i before and was super easy to switch between tunes for smog tests

I have done the 3sim upgrade a couple years back and flashed the 328i - 330i tune from Bimmerlabs on my 2009 328i e92 n52k. Also being a resident of So. Cali I was nervous about the smog test this year. (due to the new non-stock dme file law). However, the vehicle passed with flying colors. So, I wouldn't worry too much about it.
