I am one of those daft honest people who would declare it rather than risk non payout in the event of a crash. I am thinking that I may just stay as I am with the car and put the £199 towards fuel. With the mileages I cover that would probably be 6 months or more. :lol: :lol:

I know it's a different car but my current Octavia vrs is remapped albeit a custom rolling road map which added 45hp and I think about 60nm honestly ironed out the flat spot I had at 1200-1700 and made the car much better to drive fuel eco was slightly better by about 5% 50K miles later still no issues (now on 108)

I'd 100% have it done again but then again its out of warranty and I don't drive it like I stole it

One of the biggest things holding back cars is the ability to pass the emissions standards required. For example, each engine will be targetted at a set CO2 emissions bracket to save the buyers from paying higher taxes.

This can have an effect all over the engines rev range. They might take out fuel lower down in the revs so it produces less Co2 during a specific part of the emissions testing process etc.


I have a 2.0 HDI peugeot 306. That came with 90hp stock. It now runs 137hp (+51% or so). That has done 48k miles since that map, a lot of them being thrashed about on nice A/B roads.

One of Peugeot's best.
I had three 306 D Turbos back in the 90's and they were an absolute hoot even with the stock 90Bhp.
The handling was amazing and the last one a V reg had the suspension and brakes off the GTI 6.
Happy days.

Brilliant! It's amazing how many people loved their 306! Funny you should say that about the suspension and brakes. I have done exactly the same thing. GTI-6 rear torsion beam and bilstein shocks with Gti-6 front brakes as well! Great fun to drive.

Anyways, we better not drag this thread into a Peugeot thread! :lol:

Prob a lot smoother .sold it now for an auto with the remote starter app.plus only got the 163bhp version now if I got another remap it would be to benefit the mpg .got 70 mpg at 70 on the tuned 210hp on this one 163 hp doing 54mpg .hope this help s

Someone on here recommended a tuning specialist a few weeks back and I have had a quote for £199 to increase the Bhp and torque by 30 bhp and 60 Nm torque with imrovements in fuelling by 7-10% It seems reasonable but I am in two minds whether to have it done. Has anyone any sensible comments as to the value of having this done? (emphasis on sensible)
Can you say who the company is and if they are reputable? Are they based near Cheshire?

I haven't used them as this Covid 19 kicked in but one member said he was very pleased.

Makes sense, would be really interested to know the results if you do get it done once COVID is out of the way as they are pretty close to me too.

One thing that seems common between the tuning boxes (like TDI Tuning), or actual remaps like CG look to offer seems to be that most owners can’t say with absolute certainty that the car “feels faster” but more like they say it “just feels different in a good way that’s hard to explain). I know there are some video reviews of the TDI Tuning box on YouTube for the XE on various engines.

The TDI option is not as permanent but does cost more - They make much bigger claims on power increase by claiming to get the 180 XE to 238 and torque up to 509nm. So in some ways that seems way more dubious to me.

I have read online that actual remaps can be overwritten if Jaguar update your software at any point, not sure if that’s true or what CG can do to prevent you having to spend another £199

Here is the TDI box but it costs £296 for the non-Bluetooth version if you use the 20% off code plastered on the top of their site which has been there for weeks now (They provide 7 settings for power increase that you can change on the control unit under the bonnet, you can pay £50 to be able to change those from your phone).

https://tdi-tuning.com/car/jaguar/xe/20 ... g-box-chip

You can fit these yourself pretty easily from the videos I’ve seen. On the internet there’s loads of different opinions on whether a remap is the “proper” way to do it and then others that say either does the same thing, and finally plenty of people who say that neither of them make a noticeable difference.

I’ve not tried either so can’t comment from personal opinion, the above is just what I’ve gathered from a very brief look around YouTube etc.

One guy who had the TDI tuning box on a petrol 2.0 XE had a really positive review, but it wasn’t clear to me if he paid for it himself or if it was an advert but the guy seems really genuine and his channel has loads of videos about his personal XE over the years and the small mods he’s done.

There’s a video where he talks about the TDI Tuning box (including how he fitted it wrong to begin with lol, from the diesel guide it’s a bit more simple than the petrol and 2 connections)



Benefit seems to be you can put it back to stock yourself in half an hour (and re-sell the tuning box if you wanted). His first impression once he has it connected correctly does seem positive, it’s a petrol engine here but I believe that diesel turbos are just as tuneable as petrol turbos
