www.ecotekplc.com/CB-26P.htm I've just got a 56 2.0T s-line special edition and seen one of these valve things in a local garage. Has anyone fitted it to there cars and are they any good? There only about £40 fitted and are meant to improve mpg and throttle response. I have'nt got £300 odd for a remap with just skinting myself buying the car last week so i am thinking of trying this as a little mod. Any response welcome. This is my first thread after moving over from the B6 forum, so please be gentle! Sorry if link does'nt work never done it before!
