^ unfortunately California sucks, I know I live here as well and most companies that make a product that has not been CARB certified will not sell in CA. Reason is they get busted and pay huge fines I know of quite a few actually....
So most companies settle with just focusing on the 49 other states and leave Cali on the back burner. Only companies with big sales #'s and making enough money venture into CARB compliance.... They have to spend a lot of $ on R&D and send lots of proof to get them past and compliant for that little CARB stamp and most times a CARB certified product really isnt worth it..... Especially when comparing Whipples CARB tune with N Tune, whipples is such a watered down version and that's the only way they can get it CARB approved.
Now maybe you can get someone out of state to accept shipment and then in turn ship to you. I have thought about that for a tune for myself.... Just too lazy tho
