I've heard of a few people having this done from other forums to their VR's. Most have reported good results, said it felt smoother and engine felt a little more "eager", of course, this could be a placebo effect, but i'd really like some figures to back up this treatment... Before / after rolling road and Co2 output to prove what it is doing is beneficial... it was also covered on wheeler dealer... sKTp2DjugOA Be interesting how you get on though, so let us know. Pete
