My Oct 2012 car goes well enough but pinks pretty badly and I have hardly ever used full throttle or gone above 4000 rpm as a result (although this is enough most of the time anyway).
Asked BHM to check at the big service a couple of months back and was told I had the latest mapping. If this is indeed the case then there's more work to do.
However, because of my lusty acceleration but also quite pronounced pinking I sniff a large mouse. Just bought an octane booster and will give that a try but not expecting much difference.
Oh - for those in the UK or other salted roads - don't forget to clean your engine very regularly and wipe off the salt. My alloy bits are looking a bit tired and have just invested in various potions to clean and protect a bit...
