maybe it has something to do with the ASD. you can try unplugging the module in the trunk or code it off.

i coded mine off. on rare occasion i sometimes do hear a high pitch radio sound but it is not related to throttle. it may happen when i connect my phone via usb or bluetooth but it goes away and i am not bothered by it. it is hard to replicate the noise so i can't pinpoint it a certain action or source.
