If you have a v12 you may need to increase the pressure which requires upgrading the fuel pump and fuel pump modulator. I say this because the ethanol that is being added to the fuel here in the US is causing the gas to boil in the fuel rail causing misfires. MB has issued an computer upgrade to correct this issue. This may be old news to some but I did have this happen to me. The newer models can accommodate to the ethanol more than my car.
