AFM/DOD delete and emissions testing - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I presently have AFM tuned out and I'm considering a full DOD delete. Those goofy AFM lifters seem like a long term reliability concern.

Is this modification something that a California emissions shop could detect? I think the AFM/DOD is more fuel economy then emissions related, right?

What about a mild cam?

Turning it off shouldn't have any affect on the testing.

You can delete DOD no problem, but dont get rid of VVT!! We have VVT L99 camshafts coming very soon & they will make more peak & low end power compared to non-vvt camshafts!

Thanks. I've been following some of the VVT discussions and it looks real interesting. This will be a winter project so there is some time to see what vendors come up with to support VVT.
