As far the tune you can pay the cash for the handheld and use it for codes afterward.

The IM you reference comes off of which model and year(s) specifically? I've heard the 330i year 2006 would work but are there others as well? I've never done an extensive tune and I would think getting a used one off of a part out would be the way to go as a starting point.
