So for the past 8 months or so I have been getting some kind of high pitch flutter under part throttle when I give it full throttle it goes away. It sounds like me Cobb intake making the noise but tuner said its my vf52 wastegate. It's gotten to be pretty annoying cause I highway drive a lot and it only seems to do it in 4th or 5th mostly under part throttle. It seems to high pitch to be the wastegate and it cant be a leak cause it doesnt happen at full throttle. Anybody else experiencing this? Thanks Ryan


Edit: mods are grimmspeed ebcs, turboxs catless turbo back, Cobb sf intake, torque solution Tmic, dw65c fuel pump, turbo smart Bpv full recirculating

Intakes don't make noise, especially not fluttering. All they do is allow other noises to resonate and get louder when compared to the stock intake.

You're just hearing the wastegate opening and closing under heavy load.
