the ecu needs a lot of rethinking IMO. but it's ok for it's 1st stage i think.
I think you'll need to have the LPG kit re-tuned. My kit also performed poorly on it's first day with slow acceleration due to lean fuel settings.

You might also want to check/replace your air filter if it's getting quite dirty.
