I just thought I would pop my head above the parapet and say that I finally did get the remap. Not only that, but I also had the gearbox mapped as well. I would say that it is well worth doing, however the difference is not as noticeable as you would think. The reason for this is probably a positive: In the lower rev ranges, the car behaves similarly to before ie it is quick but not ballistic. "Fizzy" is actually the word that comes to mind, like a shaken bottle of coke with the lid on. So pootling is as easy as it was. It does change up a little earlier as you would expect and happily sits in 4th now at 25mph. the torque waves are wonderfully relaxing it has to be said. On the rare occasion that you can get into manual mode and above 4000 rpm and "take the lid off", it is noticeably quicker than the 550i and frankly it is slighty nuts. I do miss my days with my old turbocharged sleeper Saabs and it is nice to be back in something that outperforms its appearance!
