If it's the Td6 M57 then the GM gearbox is not up to the job with standard performance, adding anymore power is for masochists.

The M57 lump AKA the TD6 in the L322 indeed takes very well to a remap with some decent impressive power gains, however as Keith said the GM gearbox is not the greatest of gearboxes mated to the TD6 and is simply not upto the job.
The GM box typically only has a lifespan of 80-100k miles in standard form..... Remap it and it will chew through the box.
I would avoid a re-map / Chip etc...

Think outside, no box required.
The M57 is grossly under powered in the L322 170hp 405nm
In BMW Saloons it can easily make 250hp and over 480nm.
A remap just nudges the power up, nowhere near what it can do in other stock iterations. LOL
LR set the power lower to meet the GM5L40E's torque limit.
Odd gearbox.
Also tbh I'd of put the 700r4 in the L322 if I was the engineer.
But of course LR wouldn't be able to hold the RR **** reputation if they used quality parts

170bhp in a 4 x 4 is more than enough IMO. Where the hell are you going to use more power on today's jam packed roads?The M57 is grossly under powered in the L322 170hp 405nm

There is a sad obsession with ever more unusable power causing unnecessary pollution just to feel big having that much power under the right foot.

More to do with the driving style tbh.
Torque is what I'm interested in, and other stock iterations the engine produces more
You tend to also work the engine harder with less grunt.
Horses for courses, I don't feel "big" with more power, but it is nice when towing to have some in reserve, instead of matting it.
Hey ho.

I tow up to the legal limit from time to time with my M51 powered P38, never had a problem even in the hills of France. Before that I towed with a Hyundai Galloper, that did struggle a bit on the hill as it got older, but then it only had about 100bhp and weighed nearly as much as a P38.

Yep all RRs can pull well no matter the iteration.
The VM powered classic is a nice drive.

I wonder how much of the decision was BMW's rather than Land Rover's though. The original BMW X5 uses the same engine and gearbox combo I believe and also suffers the same fate. The gearbox is just underspecced for the application. And likely part of the reason the HP was kept low in stock trim.The M57 is grossly under powered in the L322 170hp 405nm

Considering Land Rover will sell you a Range Rover today with what 550bhp, then yes 170hp is not a lot of power.
Even back in the day the Td6 was pretty underpowered for what it was when you look at the rest of the market. I also wouldn't say it is unusable at all, plenty of scope to put your foot down still.

In answer, the Td6 will respond to a remap/chip very well. Although exactly which one may depend on the quality of the map. However the gearbox is on borrowed time even with a stock powered Td6 (it might already have been rebuilt???). Remapping it will likely ensure you will need to get the box rebuilt. So make sure you take this cost into consideration.
