i drive a 440 2.0 glt (1993)which ive fitted an eco-tev valve CB-26 to and found that on the motorway i can get just over 400 miles on a full tank, its a great wee widget that fits on to the servo pipe and only costs £45, its a universal fitment and found that it works best on long hall journeys, apparently can up your mpg by as much as 27%, looks good under the bonnet too as it can have a small filter on it also, duno what the mpg would be but 400 miles on 1 tank is good as far as i know, tuners dont like them but you can turn it off, if it saves £££s on fuel then it must be a gid idea, ive had it fitted to my car since i bought it 3 years ago and would definately advise getting one, ope this helps folks !
