The most expensive option is to use a "Tune" that causes you to fail Smog Test for an equipment tampering violation.
Before you buy, get a written promise that the Tune will pass Smog Tests in your State. The new Smog machines can detect ECU program changes. And in California, the old Pre-Test trick no longer works either.
The work around is to makes sure it is easy to revert to the OEM settings and do it a month before the Test to make sure the switch is undetectable and that you have no Pending Codes.If you doubt the significance of the "Equipment Tampering" violation punishments ,I suggest you Google it. Recently the costs for re-complying have escalated.
