Craig, you'll need to pull your driver's seat and pull your DME computer to find out what type of chip you have. Here's Steve's page with details on how to do this:
911Chips.com - Motronic Chip Installation Instructions
If it a stock chip, it will simply have a number on the chip starting with "911xxxxxx". If it is a Wong chip, it will have a "911Chips" sticker on it. There are other aftermarket chips that will clearly have the chip make printed on it.
