I have eliminated all other aspects of the car. Compression test checked out fine, EGR delete, almost Freeflow exhaust, intake cleaned, throttle body cleaned, boost checks out, tyre pressures, alignment etc.
This will be my feedback as of today whether it gives better economy or not.
I made a mark on the pump by one of the 3 holding bolts and turned the top of the pump towards the engine to advance. My mark moved about 3mm-4mm. It is currently at the most advanced spot. It can't go any further anyway due to the pump slots not allowing any further movement.
It now starts with one swing less and my smoky idle is now completely gone, where it sometimes would just have the faintest trace of some smoke out the back. A blip of the throttle also doesn't produce an instant smoke plume now like it used to. The exhaust doesn't burn my eyes as much as it used to when bending close to it as well.
It sounds more agricultural (like the isuzu 280DT but not as harsh - actually a beautiful diesel sound) and to my ear identical to the other pajeros I hear in town.
I took it for a short spin and the tail wagged sideways on one of my favourite gravel bends in second gear 2H, where it used to stick in 1st 2H. Not bad considering it's an auto.
The tank is now empty and I'll fill up tonight.
To today's date my consumption on the car is 14.1l/100km stretching over nearly 17'000km of logged economy on fuelly.

And this is my current consumption that will change over time if this pump advance has helped me.
