My question is whether installing one before the 1,200 mile mark makes any difference at all? Did not take this step with my prior cars, so looking for anyone with an informed opinion on the topic.

Not sure there's any hard data to support, but I'd recommend tuning after break-in to allow everything to do so in normal conditions as BMW designed them to.
I even think using the Power setting might be a bad idea as it alters the throttle settings. I used it during ED but have second thoughts about it now.
