to truely get the tune right for lpg you really want the dissy regraphed as lpg has quite different timing requierments to petrol, any dual fuel setup will always be a compromise, yes you can get both to run ok but not perrfectly well short of lpg injection and dual mapped ecus etc.

have you done any other mods eg lift bigger tyres roof rack etc that may be costing you economy?
There is a lift(2 inch I think). I don't use the roof rack & tyres are standard 31 inch (235/85 R16), so the tyres are hardly causing any excess traction.

I suspect something else is going on. Engine itself may be on it's way, but the compression tests came out ok so far.
