Hi, Check out R-tech, a lot of people on this forum (including myself) have had remaps by them, the service and customer aftercare is unbeatable.
Depending on your engine code between 190-210bhp is possible.
You will need to get a new diverter valve, Forge 007p is very good.
Some companies can supply/fit this for the remap. (R-tech supplied mine for a good price, and fitting price was included into the remap, as well as a throttle body clean).
You might want to upgrade your clutch, but the standard can handle the power.
Standard brakes are ample as well, but you can always upgrade at a later date.
Good luck! best mod for your 1.8T!(IMO) sooooo much fun
