But back to the OP, there are quite a few threads that discuss this in detail but I was wondering if you have something specific in mind that you do that the car as it is does not deliver on?. I tow 3.3T van and have not come across a situation where my first thought has been "if I just had another 40 kw and 100 n.m". Don't get me wrong, I am just as much into more is better as the next diesel head, but I am interested in the reasoning.

Thanks for the ‘enlightening’ advice. The reason I posted the pic is that LRhybrid mentioned his ‘indicated economy’ which one would reasonably assume is the readout on the dash.
Now, I HAVE calculated my own economy and overall on this trip of some 17,000km, we averaged 14.1l/100km. 95% of this driving was towing the van.
Please don’t assume that you are the only person out there with a thinking mind

Back on topic, speak to Greg at AMV. He has and ECU remap for about $1000, the figures from the Dyno I saw lately showed it was a good upgrade and reports are that economy has improved in remapped vehicles

That is a real figure of about 13.5l/100km and cruising at steady speed on relatively flat ground.

Is yours the 8 speed? They are better on fuel than the 6 speed. Note that the indicated is about 2l/100km optimistic. My fuel trip meter algorithm was reset as part of the tune and is about 98% accurate

If I post mine up I can assure you it’s within 1%

Calibration took a little while but I have it sorted on mine.

Yes it is an 8 speed

A bit off topic I know, but, with the 8 speed is there anything I need to know about towing? With my D2 TD5 I put it in 3rd with sports mode turned on. Is the 8 speed just put in drive and forget it? I understand that the 8 speed is a super strong box compared to the ZF4

Even in the 6 speed it’s set and forget, I imagine the 8spd is even better. I don’t even use Sport mode on long hauls
