Mine had a new map installed at its first service by the factory, this was mid 2013.
It did cure the high rpm detonation but a side effect was less performance all through the rev range.
So all they did was retard the timing
Which isn't really a fix. Don't think of stage one as being more power, it's just getting the engine to run safely and efficiently. That it happens to give more power in the process is just a rather nice by-product really.....
