where should I send my pfc?
 

I got my pfc tuned by SR and it isn't happening. It puffs black smoke at idle, bounces around in the rpms, but with the AC on it idles fine. I called SR and they told me that "maybe they put a map for a different car on my ecu". I couldn't believe they would even say something like this to a customer! Anyways I'd like to send it to someone else so please tell me somone who will do it right.
thanks, mario

Review the idle timing and fuel for all the maps listed her on this forum anfd compare them to yours.

Have you tried adjusting/forcing the idle speed down?
