Well I had my A3 have a look over as it had some small niggles by a friend who works at Audi and we were discussing the future of my car. I said how I wasn't sure about whether it was worth it or not to do the full monty and tune the car to it's max etc etc. Anyway he said why not just get a switchable remap, I expressed how a new clutch will cost me a bomb but he just said how he'd do it for dirt cheap (and when he means dirt cheap, he really meant DIRT CHEAP!). So, as far as I know these are the companies that do such a thing: - Bluefin - Superchips - GIAC I'm just looking for something reliable, for me & my car to be taken car of and powerful. The last review I read of a tuned car was done by GIAC and by the looks of it they seem to be the best at it so far but there in Sheffield which is quite far from where I am (South London). I haven't got Warranty so not fussed about the counter but it should meet my small requirements above. I want it to be switchable so it can go back to stock when it comes to selling it. Thanks in advance.
