Disco 2 D2 TD5 Auto high fuel consumption

Hi, everyone I got my D2 TD5 2years ago, since this year I think my fuel economy has dropped significantly, like am getting 440km(273miles) out of 70L(15UK Gallon), car is form late 98’ automatic with 10p engine mapped to around 170hp, 2’ lift, 235/85 MT tires, steel bumper font and rear. Am I over reacting or is it bad fuel economy?
I’ve checked the maf sensor and it shows 55-60 on idle at around 600 on WOT
And Injector balance is not more than -3, mostly it hovers around 0 and -2 on all injectors.
At the beginning of this year car was a the garage cause head gasket went bad, they didn’t say what gasket was previously on the car, and said they put 3 dot one, so the thickest one available. Aside of fuel economy I think it there is more black smoke at WOT.
Thanks in advance for any advice and input on that topic.

mine was horrendous on fuel around 21mpg If memory serves.

They're not economical cars, mix the TD5 with the Auto with the relatively high stall converter + bigger tires + a remap you're not going to get good consumption

Okay, yeah that converter is really dropping that MPG around the town, mine is getting around 17MPG 50/50 highway/city. Now am trying to source V8 converter but is hard to get one here where I live.

Your figures are around 18mpg.
Whether that's OK depends on your usage / journeys, I reckon...
If you're driving through fields in "low", 18mpg would be quite good ?

Mine is 2001 td5 auto, completely standard, EGRincl, std wheels+tyres, no lift, no chiptune.
It stays in "high", is properly serviced, with good components eg turbo/radiator/intercooler etc.

If I do very short hops (1 to2 miles, coolant stays cold/cool) it drops below your figure.

If I pootle around 3+ miles + stop/start traffic, up to 10 or 15 miles, I get the book "Urban" figure i.e. 24mpg.
So I add 10 gallons every 250 miles or thereabouts. This is my normal.

And on long runs (30+ miles, motorway or fast runs) I get around 30mpg.

So - what kind of trips are you doing...?

Depends much on what kind of remap you have too but with those huge tyres(10% bigger than std) on a heavy automatic that consumption is not surprising at all to me, i explained many times the bad effect of more than 5% bigger tyres especially on autos i'll not repeat again, one of many examples here https://www.landyzone.co.uk/land-rover/disco-2-air-2”-lift.389774/post-5631952
