I'm in Washington and due for an emissions test. Can a chip be burn't for emissions test only without changing my combo back to stock? If so then who can do this and is it successful?
2525 is 1/2 of the CA test. Your EGR should work, the cat should be in good condition and the O2 sensor should be in good condition. I don't know what kinod of mods are on your car, but Jim Testa or any of the chip burners should be able to help you.
I got an emission chip from Scott Simpson scott231@juno.com for $15. Tell him your combo, and I'm sure he'll set ya up without the need to do any hardware changes (only fuel pressure adjustment and swap out the chip).
