Happy Monday to all you Audi Freaks!!!! To the point. I am looking for a 1.8 bar waste gate spring for my MC. Also I read last week that someone used washers to do the same thing. Is this a valid mod, or should I just get the $45 spring? The engine has 145K miles on it. TIA Dan The Man Hamren Redwood City CA 87 5000 csqw
