Hi , there are quite a few doing these conversions mainly to vehicles like Landrovers for increase in power ,on the earlier type kits the idea was to turn the diesel fueling down to aid economy , the greatest gain is to burn all diesel injected into the combustian chamber and giving much cleaner exhaust deposits ,,I used to add a small % of petrol when towing to give the same efect which was common many years ago in the winter time , I read a while ago on the net about someone just using a small camping bottle with low output regulator and getting good results when mountain driving ,,I sent off for details off doing a conversion a few years ago now , the company was Plexus Developments & Research the sales patter looks a bit far fetched ,, like cutting the fuel bill 60% , 60% more BHP , 50% TORQUE , extended engine ( due to carbon buildup ) and injection pump life

, ,
In the end I got a petrol Mercedes on the latest LPG multipoint sequential injection and is realy good on economy its the big S Class and costs same as my diesel hatchback to run which is helped by the fact that a friend has refill tanks at his farm ,
