CA testing has two tests - assuming that you get the 'standard' smog test. Every year a small percentage of what CA thinks are 'high polluters' get randomly selected to have a dynamometer test which is more rigorous.

Anyway, the standards for the standard smog are (This is for a 1988 vanagon - standards vary by year of manufacturer)

2500 RPM test maximum allowable:

HC PPM 180
CO % 1.0

Idle RPM maximum allowable

HC PPM 120
CO % 1.0

If you have the chip and the rest is in good shape, should pass.
Add an adjustable pressure regulator and just turn it down a few psi for the
test.
Mine with the Chip, rockers, mild porting and other changes passed my local
emissions test.
What are the requirements for CA testing?
