K03 247bhp / 295lbft, so nothing serious... reset fuel computer today just before some very spirited driving over a few miles (completely empty track)... returned 10MPG!!
Had oil change / plugs less than 1k ago, all warmed up, no error codes.
Just thinking there might be something wrong with that sort of MPG. Is this about right for track driving?
I've noticed that the MPG has been getting progressively worse in normal use too.
