Yet I don't think there has ever been a case of a remap causing the failure. It also isn't that the engine isn't strong, there is just a potential issue in the design.
Factory examples produced up to around 300bhp in some models/regions.
Maybe, but?
This is a bit contradictory.
I was just pointing out that maybe not the best engine to do a remap on due to its reputation in the Discovery.

Id give Gareth and Empire Tuning a ring, he can give you the best information for what you want.
I read that they stroked the old 2.7 to make the 3.0, and this made the slightly dodgy crank even weaker.
I can remember when the 3.0 was new and all the owners were saying sell your 2.7 as the new 3.0 as it is much better!
I think the 3.0 in the RR makes around 300bhp?

But they aren't related. A stock engine stands just as much chance of failure, a remap will not alter the odds.

Also worth noting that the TDV6 was used in lots and lots of vehicles. Loads of Land Rover products from a D3, thru FFRR, RRS, D5 and Velar. But it was also used in a whole heap of Jaguars too, as well as Ford's, Citroen's and Peugeot's. And is still used today in the current Ford Ranger and VW Amarok.
Highest factory output was 302bhp, which I believed used the same basic engine/crank as the lower output versions (you'd need to fully check this). But proves the engine is more than strong enough to handle more power.

All - thanks for the information and feedback - will give this some thought before parting with hard earned etc. etc.

I agree with that^^^
for the OP: IMO a well made remap can improve the engine's functionality and reduce the stress on it despite of enhanced power or torque but even if no gain in this area i'm sure it won't hurt... i dont think that the remap would cause that common crankshaft issue which can happen anyway (or not).... if i had a D4 with a decent mileage which didnt fail yet i'd remap it without fear... though if you decide to do it and it fails after dont blame me please.

100% agree + Gareth would do a full health check before hand to check all is well.
As with anything remapping can highlight any issues with the engine you currently have.
