Benny...can you spill the beans on the 599 MC Shift upgrade please?! Thanks.
It's a TCU upgrade, so adjusts the transmission control to more closely resemble the shift times of the 599 GTO. And jolly speedy they are too!
It requires a SDx machine loaded with the GTO software and takes not quite long enough for your coffee to get cold. The challenge is finding someone with the right kit and software to do it. Hen's teeth / needle in haystack / etc. But worth the hunt. It'll make you fall in love with your car all over again and even more.
Drop Benny a PM because he might know someone*. If he doesn't reply, post back on here and someone will give him a prod in the ribs. He's lately been spending too much time under the bodywork of a German lady, so is a bit distracted.
