Where to install Stillen Supercharger in LA?

Specialty Z is in Chatsworth and Stillen is in Costa Mesa. Both locations are a doable drive from San Gabriel Valley.

Also only the Stillen Supercharger is CARB certified, with the Stillen tune. Thus if you obtain a custom tune, you may not pass the emissions testing -- or you should be prepared to default back to the Stillen tune at the time of testing. Hence, you should check with Stillen regarding this issue.

Thank you for that info! I am not too sure if Stillen will install it because they advised me to drive even further away to install the kit even though stillen is like 30 mins away from my house lol let me email them to see if they can install them. Thanks !

there isnt really a way for to tell that you are running custom tune though is there? AFAIK smog is only visual + codes

I understand that if you live in an enhanced smog requirement area (most of California), the ASM2 emission test checks the vehicle current tune on the ECU against the manufacturer's tune. Thus, if there are dramatic changes to the engine timing etc. you can fail the test.

Interesting, I did not know that as I've not heard someone fail the smog test due to a tune. I wonder how if they'd be able to detect a custom tuned stillen kit (assuming through obdii)

When I tune them they always pass. In addition, if you do run the stock stillen tune, you will fail the sniffer test but they don't do that anymore.. Usually the other symptoms are check engine lights that will come on weeks or months after the kit is installed. Their tune should never have been approved, the cars never run right on it.
