    Just wondering would a service and octane booster plus super unleaded mean better emissions for a non cat car or have I had too much red wine

      Higher octane = more knock/pinging/pinking/pre-detonation suppression = more difficult to burn

      Emissions-wise, you are probably better off with a lower octane fuel (petrol/gasoline) from a high quality supplier (not Tesco, etc).

            Get someone like Dimitri to make a selectable map for your ECU.

            In mot emissions mode it runs so lean it hardly registers

            That would be cool!!!!!
