Not convinced the D200 to D350 is as straight forward as you think as from memory it’s not just a tune that is required - some mechanical work may also be required and changing of components

Prices do vary a fair amount, similar to those offering CCF activations for things like ACC and dynamic mode - range from £50-300 for each from a lot of places
For those it's worth getting the GAP tool or the JetPro software, the latter of which can do the power upgrades I believe too |

l think you can upgrade the D200 to 300hp but not 350.
Still a worthwhile increase in power. |

There is at least one company offering the 350 upgrade for pre MY25...

From the D200? That's quite a step up, 75% more bhp

Potentially slightly different cooling systems but the engine itself is mechanically identical I understand
No different to other manufacturers who map up/down based on models, but certainly allows for a bit of headroom if looking to increase outputs and some of the gains from factory spec are enormous |

I’m sure I’ve read somewhere the turbo/turbos are different but hey the folk using a hacked Pathfinder would know - would stay away from a non genuine tune, ok not from a LR dealership but an actual D300/350 map etc. Gas, Grass Or Ass - Nobody Rides For Free

You can Upgrade from D200 to D250 with just Software changes. With D300 comes a auxiliary cooler on the front side.
So with that in mind, from D300 to D350 is also just a software change. New Defender 110 D200 S | Freelander 2 SD4 Metropolis |

l ordered a D200 back in January 2022 as it was fine for my needs. After a few months waiting (delivery was quoted as 12 months) the dealer told me l could not have the D200 as it was "not currently available" and l would have to have the D250....take it or leave it. The cost was an extra £3,000, a nice little LR earner for a few lines of code. The D250 is great but after what l paid, your quotes are a bargain!! |

I’m pretty sure the D200 is a I4 while the D250,300,350 are an I6. Therefore, you can’t upgrade it into a ‘true’ D350. But I guess you could upgrade it into 350 hp if the engine permits in terms of strength. Current (LR):

No, you are wrong!! D200 is not a I4, it’s a I6 too!! …in another order of things…These guys, Venture Automotive, in Bolton claim to do it, to everyone from D200, D250 or D300 and also remotely anywhere in the world!!

Oh, my bad. Thanks for letting me know! D240 must’ve been the only diesel I4 then Current (LR):
