I beleve its always been in the radio. Its just that I'm amplifying it. I didn't have it before i upgraded. And it does go away when the TB's are unpluged.

You will still get that noise in the engine bay created by the throttles as they turn on. The radio muffles it/ silences it.

The noise in the bay is different from the radio. You can confirm the noise if youre able to open your throttles with the vehicle off. It should be a high freq hum changing with throttle angle.
