QUESTION.............could it be cos Im using 95 octane juice ?? ie cos of the change in exhaust pressure,air intake,slight power change,ECU reset etc etc could it be cos I should now be using 97+ octane ?? Just an idea cos my ex gf's Scooby used to run perfect on 97+ but totally !Removed! on 95 ! And before you say it yes I know that my Beemer is no Scooby,or has the power like a Scooby.Its just an idea ??
