    Food for thought, I have a 98 GU TI duel fuel and I wanted to fit a duel battery so I chucked out all the factory air box and shit and made a s/s 3" snorkle with a scoop across the top of the windscreen that has a narrow panel filter in it (the same as the ones used on V8 holden OTR intakes) and now I get a lot better fuel ecconomy on petrol but on gas it stalls every time I back off the throttle to coast up to a corner. I put a vac/pressure diagnosic gauge on the intake duct next to the gas mixer and at 30km/hr with my foot off the go pedal it was showing +0.12 bar and I think that pressure is upsetting the LPG flow.
    If it does'nt go hard, Stroke It.

    I had the same problem. Slowing to a corner engine leans out and stalls. Fixed it by turning the snorkel inlet to face backwards. Not so easy for you.

    25+ city/highway, 90 litres useable lpg (115l tank). 2" lift, standard AT tyres, alloy rack, no drawers or other heavy objects (water etc). I've seen 3 different (and recommended) lpg specialists, valves done regularly, new condensor, plugs, leads etc. Always the same economy for the last 3 years.

    Depending on the setup you can connect a balance pipe back to the converter top stop this happening.

    The 4x4 place I went to checked the valves, filter, leads, plugs and advanced the timing. They suggested the plug I am using are not ideal but did not expect there to be any impact. Not expecting any change but will know after the next fuel fill up. If no luck I will go to "The Gas Man" in Seven Hills, NSW. Anyone used them?

    Should be able to get it lower then that. I drove mine from brisbane to melb and back and got in down to 17L/100km. Reset everything (disconnect battery) and then take it for a long drive. Obviously not a 4000km drive but something to get it to relearn properly.

    I typically fill up at 250kms however I just fill up each time and work out the L by the km driven, eg last week I filled up and got 74.8l with 249km travelled.
