Cannot speak for other manufacturers but do know that mainly the only thing to suffer from introduction of more power to the diesel Range Rover is the torque converter, it being smaller that the petrol version. More heat build up in the converter from absorbing more power causes overheating of the converter and this causes the internals to warp. That is the reason Range Rover recommend NOT fitting the driving lamp to the N/S position in their service sheets. Doing this blocks off the air flow to the transmission oil cooler. Possibly not a problem if the vehicle is used just for driving around, but if a power chip is fitted and a lot of towing is done it could create major problems with the torque converter, especially if your vehicle has a few miles on it and is not in the first flush of youth.
