MPG in my 300Tdi auto

Hi everyone. I have a discovery 1. 300 Tdi. Auto. When I first got the vehicle the injector pump was controlled by "fly by wire" taking its commands from the ECU. This however broke down and instead of getting it fixed, at a great expense I set too and fitted a manual pump. Unfortunately someone had played with the diesel screw and the turbo boost settings. After matching the pump to the auto gearbox I set too adjusting the pump to give good fuel return with decent acceleration. The engine is in good order. Starts with just a touch of the key and doesn't smoke even on hard acceleration. After monitoring the fuel use age over many weeks with adjustments to get what I feel is the best performance the disco is returning 24mpg round town and my best was 36mpg on a long run travelling between 50 and 60mph.
With me being new to the land rover scene is this a good fuel consumption or could it be improved.
Your replies will be most welcome. Thankyou. Zuggy.

36 is about as good you'll get

I thought 36 mpg was about right. Its taken some weeks to set the pump up but I'm happy now with the performance. Matching the auto gearbox to the pump was the tricky part.
Anyway thank you for your reply. Zuggy.

My auto does about 22-24 mpg, can get it as low as 16 when towing my single axle caravan. I'm giving it to a good diesel mechanic for a spell so he can test, check and repair things, give it a decent full service etc and get rid of the bit of smoke it's now producing, it's over fuelling for sure. I'm kind of hoping it'll be 'revitalised' when I get it back. Is it a major job to get the pump changed from EDC to a normal one?

My EDC tdi auto currently returns 32mpg. That's a mix of motorway and local stuff.
Although, I would add it's desperate for a service which will be impacting negatively on that figure.

Im getting 27mpg average just doing 4 miles across town to work. Gearbox has just had a full service, engine has had a full service.

With a well written chip for the ecu it should hopefully get to 30mpg average.

And...(fingers crossed)... an uprated torque converter should aid mpg and performance as well as towing efficiency.

Im in the process of trying to buy a house at the mo so the 400 odd quid its going to cost will have to wait.

It would be nice to get it up to averaging 35mpg over my daily drive. We will see though...
