Hello OK in that case its likley to be an issue with either the LPG gas regulator or the MAP sensor that is typically used in these conversions I'd 1st check that the gas pressure at the injectors is up over 3Barand if thats OK check the the manifold pressure sensor ( MAP) where its attached to the inlet manifold if you cna tell me the amke of the LPG system thats fitted then this would help diagnose the issue
