what are the symptoms of a bad wastegate actuator?, I have had this on going problem with my evo now and it is getting worse everytime i floor it...needless to say i don't get into full boost anymore, in fact i had to turn the boost down so the sputtering wouuld stop, but then it started again and i am only running around 14lbs of boost, One of my friends says fuel cut and i suspect actuator. I haev already changed my plugs and hooked up my boost controler both ways, cheacked for bost leaks and nothing, so i am at a loss. I am going stand alone and big turbo soon so i am sure the problem will go away once alfred gets his hands on it, but it would be nice to drive around my car at its full potential till then.
