Yes you can install the Cobb AP with the ppk. Once it's installed, your stage 0 will be a stock like map (non ppk). But if you completely uninstall the AP I believe the DME software is completely restored to what it was before, in your case ppk. If I were you I would just email Cobb this question for peace of mind sake.
