Sorry for writing in English, I only study here in NL.
I have a quite specific question and really hope to get an anwser here

I have a 2003 330d family sleeper Touring.



The car has been remapped at Hartog Tuning in NL few months ago.

According to Gtech which obviously can be wrong by some % ; it has 272PS and around 595NM.
40 - 220 kmh vid from today ---> http://picapic.eu/video003.3gp
It is a rather strong custom program that I am very satisifed about. The only problem is that any further developments or even hard driving from low rews at this point is limited by the flywheel.
Because of the to high NM the flywheel causes the car to go into turbulences. I know that a reasonable solution would be just to cut off some of the NM but it would be just too easy.
Does anybody know if the new 330 or 530 models have somehow "stronger" flywheels and if it can be transplanted together with the clutch into E46 M57TU. I tried to make an reserach on that but unfortunatelly without any results.
Since it does not cost 99E to buy, I would like to inform myself in advance

I hope somebody had a simmilar problem here and tried to fight with it already ???
