How do you know if a PT has been upgraded?
Hi,
I just bought a used an '03 PT Turbo with 27 K on the odometer. It has a K&N high flow filter on it.
I was wondering how to tell if a PT is upgraded or not barring a dyno test. The computer has an "Authorized Software Upgrade" decal on it with a pin number. The upgrade was done in June of 2004.
