Welcome to the club Rich, the best way to release more power is to fit a Supercharger; the people to talk to are TDI who advertise on this site, Mark is your man there. There are a few members with this mod, I'm sure they will answer any questions you may have. As for connecting your radar detector I can't see it being hard, a simple case of taking an ignition controlled feed. Any decent auto electrican should be able to do that for you.
