unless...GTM really has that VVEL cracked

Be warned though, that will fail you when you come up for smog eventually. The emissions test checks for sensor readiness and if a set of o2 sensors are turned off, they will fail the readiness check and you fail.

Otherwise, keep adding o2 bung extenders until you don't get the code anymore.

ill worry about that in 6 years (isnt it 6 years for a new vehicle in california?)

regardless..couldnt you just change the tune on the fly to the stock tune as per the UpRev allows, and hope the CEL doesnt go off during a smog?

or screw it..i know some places where i can pass smog
