My T5 engine had the same problem by running lean at full boost doing 140mph down the autobahn, having been pushed hard for the previous few miles at 130-150mph. That is on a standard map, never having been anywhere near a tuning company.
I've no doubt that in all probability that the map may have contributed, if not caused the issue in this instance... but if it can happen with a standard car... etc?
