I bet they have, I remember buying an Eco-tek powerboost valve £75 - the company who make them have an expert called Tim, talked to him for days, I had one on the Cosworth and it worked great. He convinced me to get one for the V6....bad mistake as it throws lambdas out and unless you fit two only cylinders 1,3,5 benefit as its connected in-line to the brake servo vacuum.
Eventually they made a statement on their forum that it wont work unless you fit two!
Basically quote Seems to be a distinct lack of data to back up improvement claims, and folk that claim it works could easily think so due to "placebo" effect....because of the rasping noise....got a refund waste of money lol
