Just to add, he’s had the cats removed and the dpf delete and remap around 330bhp and ridiculous torque figure (wonder who he’s following? ::) ::))don’t know how long it will last but been 3 years already and he certainly doesn’t pussy foot around, however I know he’s trying on this journey for mpg as I asked him to. :y

I'm generally regarded as one of the most light footed here and can eeek the most MPG, my record was 76mpg with my VW back in the day on a very long motorway run at truck speeds.

I'm also strongly considering XF of that vintage, so keen to know outcome. But when a JLR employee here can get close to those figures, but on much newer 2.0 inline 4 pots. Not to sure how you can get 60mpg average from a 3.0 apart from the odd second on an instant consumption view.

It can be done  :y

Ahh ok so it’s been fiddled with a fair bit!!! Might explain much improved mpg over standard.

How was DPF delete done? As I recall MOT rules now check if ones fitted when it should be.

No comment on any of that ;)  He says it’s a little better since the remap etc but not a lot,however it now has 50 bhp more too! And......... he changed the inlet manifolds before the map one was slightly leaking, Jaguar says they aren’t a weak point but they are, they have not said but the new pair he the fitted were discreetly upgraded from the original I would bet.

It might still be fitted but it might have been hollowed out just after a regen.  :-X

https://mobile.hyundai.co.uk/offers/scrappage-scheme

£2,700 off the i40. The diesel version of which will get to John O'Groats from the south coast on two thirds of a tank. And you won't have to waste time opening the bonnet :-X

Is this figure off the full list price, or a hard negotiated figure?

One is much better than the other.

Off the list price, but no harm in asking for more :y

Also any preregistered stock should be cheaper still :y

He loves his car and when I told him his mpg was being questioned this was his response



Right let's have a bet then tomorrow I will be driving 350 ish miles I will reset when I leave my house and video the reset and video the trip computer reset then when I finish up at carlisle we will see what average I've got
I don't want his money. But get him to do a brim to brim test and calc manually. Then compare to FC.  He will find, if he's man enough to be honest, a significant discrepancy.

If he gets a genuine high 30s, even on a run, our ideas of Miss Daisy are radically different ;)

OK, many remaps do make the FC even more out.

So genuinely interested in the real figure.

Downhill, backwind, and not me driving.

I reckon it will be possible to get (genuine) high 40s/low 50s are a constant 50mpg, which will read over 60mpg on an older Jag FC
