My 05 diesel (6 speed ) was remaped and the exhaust modified to 615Nm 3 years ago and I personally haven't experienced any problems, and torque is by far more of a problem to the the drive line than Kw ( HP ) A point I made to one of our members who asked me about performance increase to X5s was I would think it far less of a strain on the transmission or any other part of the drive line by remaping or supercharging than it would be towing at somewhere near capacity for extended periods, My E53 has a towing capacity of 2.5 tonnes (metric) think about the exponential forces of pulling that up an incline or the increased load at speed due to wind resistance of the towed vehicle. In AUS the same trans has been used for many years in our GT Falcon (Ford) which developes around 428hp/433fp (590nm) so obviously Ford decided the 6 speed was well capable, and still has a tow capacity above this. Cheers.

The ultimate hp/torque capacity of the transmission as specified by the transmission manufacturer likely has to do with the strength of the internal components, things like shafts and bearings.

When discussing things like trailer towing and duty cycle, we are getting into the system limitations, not just the limitations of the transmission itself. Just by way of examples, the system includes a cooling circuit, and software that could manage torque limits by softening shifts. If another manufacturer used the same transmission and didn't manage the engine controls to reduce power during shift events, the transmission would see very different load profiles. Conversely, if the vehicle manufacturer didn't need 600 nm of capacity in a specific application, they wouldn't put the cooling system and other components into the truck to accomodate that limit, even though the transmission itself may be capable of that torque limit.

Not launching (rolling resistance) helps too... it gets as much torque as you give it.

so has anyone done it yet? they have the supercharger up for the E60 550i (same 4.8i engine) but nothing under the E53 X5 4.8is section.

Sorry to ask here, but since this thread has no big deal talking about ESS S/C,
I have an E60 3.0d 04, would the remap fit? where could I get it and is it possible
to get shipped without bringing in the car? As I am not in US. and much would it cost?
