Apologise this has taken so long I've been busy driving the golf
Anyway as promised I took the car to Carbon a couple of weeks back now. I watched and chatted to the guys from start to finish which is a nice touch they didn't seem to mind at all and its pretty reassuring (not that I had any doubts) as its immediately obvious they have got mountains of experience and have this re-mapping stuff down to a fine art.
In brief the ECU was out and dismantled with great care half an hour or so later put back together looking like it had never been touched since leaving the factory.
I quick test drive later and I've got a massive smile on my face. What a seriously huge difference the car feels much more powerful and responsive and doc 3rd gear is mint.
For me the best feature of the re-map is how once you have adjusted to the increase in power the car feels 100% factory standard the delivery of the power is perfect there is no sudden wave of boost just a smooth pull all the way through the rev range.
Thanks doc for making a good car even better and to anyone else reading this driving a GTD I would highly recommend a trip to Carbon.
