Thanks to Rolands post from a while back (thanks Roland!) I realised that my car is pinking. So today I removed the suerchips remap that was part of my Lohen 225 package. It did worry me that I was getting much better mpg and no poppage from the exhaust and so might be running lean. Like a retard I did wonder what that very light tapping noise was when the car went past 5k rpm. Sounded like metal filings being dropped on a piece of sheet metal.
So... as I couldn't get hold of Lohen or Superchips I though it best to remove the remap... and guess what... after a few runs the car actually felt quicker and the tapping sound was gone.
Naturally I'll go back to Lohen to ask if everythings ok as it may just be my car or my ears but unless the superchips guys want to remap my car on the rolling road next time I don't think I'll be putting the map back on anytime soon.
Also added a nice new roof graphic to the car today... can you tell what it is yet
