All you can do easily is chip the car to raise boost I think. Take a look at northamericanomotoring.com, theres much more tuning related posts on there, but you have to deal with the differences between US and UK cars as already mentioned on this thread.
Apart from the JCW tuning kit I think there's only a couple of UK options, Superchips and Morego of those I've not any posts from anyone who actually has one fitted, and of course you'll kiss your warranty goodbye. |
