Mine says 640Nm at maximum chat which is 472lbft. That is about what it's supposed to be making although whether that is the demand figure or the actual figure I have no idea. Thinking about it, I'd guess that it's the demand figure according to the throttle pedal position etc. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

How does it measure it, if at all?

No need for any vehicle details but basically if there was a mechanical issue with a trans for example, part of the interrogation would be to see how closely matched to each other the torque signals are between engine and trans.
Very easy indeed for us to see and obviously that level of increase would be somewhat outside of the production tolerances we'd expect to see.

I was giving an example. Ok, imagine for a second you blow a turbo then... Regardless of what we may or may not offer in future, the fact remains that this particular example isn't to the spec it was built, is all. It's your car, you decide what you wish to do.

It's easier than delving into engines or gearboxes.. Just ring his insurance company as he has to advise them of ANY modifications or policy is invalid ! 5.0 Ltr Superchrged RRS2, Chile Red, Sideways out of junctions!
TDV8 HST Stornaway on a 08.. remapped.. now gone and replaced, was a mighty fine car..
4.2 SC First Edition when they first came out, quick car!

Try looking at it from the other side of the fence. Imagine you're a manufacturer who a dealer calls and says he has a customer who has presented a relatively new car with an unexpected failure mode. Are you just going to front up the parts and labour, possibly a new power unit to boot, or would you kinda take a look first?
I'm not saying every manufacturer will check every car - unless its Porsche - but just think about that.
