I have an '08, running DINAN Stage II software. I hear and have read that the newest OEM Software for the M3 has some improvements that are felt compared to the older software versions. I wonder if since I'm running with the DINAN, if I had my BMW dealer update my M3 with the latest software and then re-load the DINAN, would there be a better performance gain with the engine? IOW, will the DINAN software re-map everything and cancel out what ever improvements the BMW software has? I have to run a stage II in order to keep the increased emissions CEL from coming because of my HFC X-pipe. I just want to know if its worth getting it updated and paying for it. Thoughts?

Cheers,
Rob
