    I can't comment on gains from this but I would highly recommend that if you do, have the inlet valves and properly cleaned as they will be absolutely caked in burnt on carbon and coke. I did this on mine as it was misfiring on idle. Made a big difference. It's a common problem on the direct injection engines.
