Guys, My car is totally stock but today as I was joining the motorway I gunned it around a bend in order to get in a gap in the traffic, and as I was gunning it I thought I heard the car ping... Admittedly my fuel level was under quarter way...are stockers prone to fuel surging and pinging just as much as modified cars? I always run 98 Octane (Shell or Mobil)...anyone had this sort of experience in a stocker?
