On your 10psi pulley upgrade it says 98 octane fuel is required. If i was running standard LPG I know this would harm performance. Please suggest would upgrading to injected LPG help this?

Given the octane rating of LPG, it wouldn't be a problem. In fact, you would technically be able to run more boost then 10psi, however, to play it safe we would only recommend you to stick with 10psi. It would definitely help.
