Vf supercharger emissions readiness

I’m looking into a vf supercharged z4m. Does anyone know if this kit will pass obd2 readiness test? I am not concerned with the visual, just the obd2 test.

It depends on the tune, and you will need to talk to VF or a current owner to get the info.

My ESS and G-Power cars were reflashed with Euro-based tunes, which do NOT pass OBD2. European emissions standards have a different drive cycle and don't monitor the secondary O2 sensors in the same fashion. VF is US-based (California), so they probably used a US car in their development. It's possible that it will pass OBD2.

Side note - ESS has a US tune option now.

Thanks. I sent an e-mail to VF and asked the seller as well. The car still has the stock cats...so I'm hoping they didn't disable any of the emissions readiness checks..
