these are amazing engines, my mum had a mapped 535d on a 57 plate, the BHP was similar to yours, but your torque figure is huge ours was at about 550, and that was almost comical on the road with the auto box and instant gear changes, she has a 07 M5 tourer now (V10), and IMO the diesel was better all round, M5 is very jerky on the up change, im going to buy my own 535d next year hopefully, truly amazing engines. great results on the torque
