Remember, with a remap, you don't use all the extra power that much, only overtaking etc, however the drivability with a remap is another subject altogether. In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures
Gone - A couple of RRS, A couple of Disco's. However thinking of another Sport.

It can be if the transmission is not healthy though. Even with a healthy box, a bad remap could cause damage - it's about power and torque delivery, rather than outright power/torque.  Visiting from DISCO3.CO.UK

The SC does have the speed, but the torque of the TDV8 will put the gearbox under the most strain. It's the torque delivery of a badly remapped diesel that can be the real killer.  Visiting from DISCO3.CO.UK

As I said, have a chat to Pete Bell at BAS, he will not lead you down the wrong path. In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures

Yes, the 6HP26 has an input torque of 650Nm. The TDV8 has 640Nm as standard. No doubt the 'box has a factor of safety built in and can actually handle twice that but we'll never know.

I wonder if LR fitted the same uprated gearbox to the TDV8 as on the SC... 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
