I am currently running P08 software, but still have some part-throttle pinging on crappy CA gas. I want to upgrade to P09 software, but apparantly there are both P09 and P09b versions. Do you know what each does, and which would be better for me? Thanks. BTW I was really impressed with the performance improvement of your intake kit, just the DV valve sound itself is worth the money! TIA.
