my Cruze has been having some trouble building boost. This turbo is less than a year old. I know there’s lots of other posts about turbo problems but I could never find exactly what I was looking for. When I accelerate I can hear the wastegate opening and closing while Im on the gas. What causes this???? What do I need to do? What exactly do I need to replace? I think I already need to get a new turbo I think my wastegate is shot. It’s getting stuck open. I took of the actuator arm so I could open and close the wastegate with my hand. It felt a little stiff when it was opened up. This is obviously a problem but I don’t think that’s the main problem. I don’t think that would cause the wastegate to open and close under acceleration. I bought a oem spec turbo. It was a Stigan turbo. Is the ECM thinking it’s making too much boost and trying to regulate it? I’ve been having this problem with the turbo for a year nonstop. Please tell me what to do! I don’t care how much it costs
