One more question....

The Dinan tuner at the BMW dealership told me that the ecu could take a couple of days to adjust to the changes.

Was there a noticeable change for those of you that got the Dinan tune (after the ecu finally adjusted)?

I didn't notice a massive power change. I can tell there is more power there, but nothing earth shattering yet. I can feel it more in the top end than the bottom end. I'm assuming that the bottom end will get better after the ecu adjusts.
Your experience sounds like most member's experience with Stage 1. Stage 2 delivers much more power at the low end than Stage 1. Maybe they need to re-install the software.
