Well, I chance to investigate a hauliers MAN 44tonner today, one of five which he has fitted with LPG fumigation in the interests of decreasing fuel costs .
It's a Mercury system, and fully integrates with the fly-by-wire 14 litre lump and ecu. In this case it's only active between 13-1700rpm with the turbo boosting at 10psi or higher, but can be setup in various ways including adding HP/Torques.
In this case it is running at approx the factory output of 480hp. The mercury system uses individual injectors like a petrol/gas car might rather than filling the whole intake system -large on a truck- full of flammable gas mix.
At around 6mpg on straight diesel, the truck would cover about 900 miles per tank. With 150l of gas onboard also (at 70p/l ) he is adding a further ~450miles for just £100 worth of lpg fuel.
He reckons the system will pay for itself in under 10months. The only limitation is truck cannot go on the eurostar, but it has a wonderful propane / adblue / catalyst exhaust aroma!
Food for thought gents.
