Was able to get the stage 2 map from PTF. They had to push it to my account since it's still not released to the public. Going to be flashing tonight and taking it for a test drive tomorrow.

Is the tune specifically for Z4 M40, or are you using m340i/supra tune? Not sure if that is even possible.
I was hoping cold starts would still be ok with valves closed with the new downpipe. Are you planning to take videos? cold-start and drivebys etc?
