Yes, I have been looking at this recently and doing some comparisons.
The auto box in the 520d, 525d and 535i are all rated at 400Nm. The 525d and 535i engines are both rated at 400Nm as standard. The auto box in the 530d and 535d is rated at 600Nm and the 535d is rated at 580Nm as standard. The 520d engine is rated at 350Nm.
Remaps of 525d and 535i add about 80-120Nm whilst a remap of the 535d will add about 70-100Nm.
Thus where you rempa, the 525d and 535i gearbox rating is being exceeded by more than that of the remapped 535d. However from what I have read, it is the form of the delivery which can do more damage than the out right numbers.
Hartge don't list the 271hp/591Nm option on their website any more but ESS still list one for 280hp/600Nm but with the caveat that this is only for a manual box. Their phase 1 remap is marketted as 550Nm.
Elsewhere, I have read that the gearbox has a 20% safety factor. Frankly it must have some factor as BMW wouldn't put a 400Nm gearbox on a car rated at 400Nm! My hunch is that you wouldn't want to go much higher than 500Nm on the 525d. In real terms, this is probably the limit of a sensible remap anyway.
Based on this, the 520d and 530d are the ones with the most safety factor in their drive trains.
I for one would have been happier remapping if the 525d had the stronger 'box, but there it doesn't always work out that way!
Regards,
David.

On RealOEM, the manual box listed for the 525d & 530d is the same. However, it must not be rated to 600NM as surely the manual box would be available on the 535d, which we all know is auto only (which I understood was due to the manual not being strong enough?). So presumably the manual must be somewhere in between, 500 - 550NM? Certainly would be interested to find out.

Intake manifold- LCI 525d - http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=40 - E60N 525d INTAKE MANIFOLD- WITHOUT FLAP CONTROL
Intake Manifold pre LCI 530d - http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=40 - E60 530d INTAKE MANIFOLD- VACUUM-CONTROLLED - part is: 01 INTAKE MANIFOLD WITH FLAP CONTROL
Spot the difference in the naming conventions...
Does this mean no swirl flaps????? Or am I hoping...??? Or is it to do with the Vacuum hose and connectors? Anyone know? Has anyone dared to take the inlet manifold apart to check on the LCI's - especially the 525d????
Here is the E39
530d Auto (2001) -http://www.realoem.com/bmw/showparts.do?model=DL82&mospid=47545&btnr=11_2837& hg=11&fg=40 - E39 530d INTAKE MANIFOLD AGR WITH FLAP CONTROL

I must say - I've been sleeping much better of late...the plan is to keep this baby for at least 5 years. So unless the Turbo decides to packup, it looks as though I'll be OK 
Seriously - it looks as though all 18d and 25d engines (i.e. those of the least power in the 4 and 6 Cyl's oilers) don't have those dreaded flaps - which I think is good news. I've also asked if 7's or X's have suffered over on BMWLand forum and so far there are no reports. So if BMW did change the spindles as rumoured in 2004/5, the ones made 54/05 onwards (Incl. 535d and E90 320d) should be OK...time will tell...
