I would definitely have the DME reflash done by a trusted indy shop. What I'm hoping to find is anyone else who has done this for their E53 M54. I've read much over on E46Fanatics by guys who have done this for their E46's. Was wondering if there's benefit in doing it for my E53. I'm looking forward to the possibility of deleting my SAP and installing new headers and removing my cats. I understand an EU2 DME reflash would allow me to do all of that.
