I was wondering if any of you guys know what my problem is. So basically i’ve been having turbo flutter for a couple of weeks now and my turbo only goes up to 5 psi. I also the p2261 CEL a few times but it comes ans goes on its own. The only thing i have is an aftermarket cold air intake. I also replace the turbocharger wastegate solenoid but nothing changed! pls help i have a 2012 coupe 2.0t
