Terraclean

Has anyone carried out a Terraclean petrol and induction clean on their C5 RS6? We had this done on my wife's S3 recently and the car is running very noticeably better and is quicker with greater fuel efficiency. This is supposed to be a preventative measure to protect injectors etc but I would be keen to hear others views/experiences. If the effects on my beast are going to be the same as for the S3 then it will be £145 very well spent!
