Diesel boost compensator

I believe IMHO they are a "nice to have" but if your turbo is set up properly, not really necessary unless you are in "alpine" regions a lot.

Basically a lot of extra dough for a small gain..... I don't have one and don't see the need personally. My TD42 turbo barely smokes at all when driven normally. Cheers

Thanks for info so far.
I just feel that the system on my ute does not compensate as well as it might for varying load/throttle combinations and the fuel consumption of diesels is rapidly being caught up by petrol engines which, if they did not seek to outdo each other with top end on paper figures, would be closer to diesel numbers.
Higway mpg figures with a Commodore sedan are better than my similar weight Triton. Surely not all in the wind resistance as Triton is fairly clean & canopy & tub is in line with cab 100%.
Commodores achieve 8l per 100kms & Triton does 10l 100kms at 100kmh. I need a tail wind & 80-90 cruise to achieve the same.
Compared off-road & in bush with petrol 4wds its well ahead .

You'd probably be surprised at the difference in drag between your Triton and a Commodore- not just wind but also drive train, tyres etc.
Try comparing with a petrol Triton for a more valid comparison.
P.S. My Patrol gets 10l/100km @ 100kph on the highway.
Cheers

Thanks so-far for all replies. Anyone know what they cost?

Ok Comparing the 2.5td with the 2.6 petrol Paj from all reports they do about 21mpg highway (about 7km/l). The same motor in a Manual Sigma which is much lighter than a Commodore from my own experience has trouble doing over 30m,pg nowhere near the later larger Commodore but few older 2litre petrols seem to do much better except for some Euros.
