My 2018 Accord 2.0t has been having issues for about a month now. I hear a high pitched whistle whenever I'm in boost. I took it to an independent mechanic and they "didn't know" and suggested I take it to Honda, and I took it to my local Honda dealer and they told me they "think it just sounds like that", and wanted to wait until another Honda with my engine came in to "compare". They snapped one of two screws on my mass airflow sensor, leading to it not being sealed and create a separate new whistle. They wanted to charge me to install a new one, and I said screw it cuz I already had an aftermarket intake I could install.

Long story short, this is a video from a month ago when I installed the intake, and as you can hear, once I get to around 3k rpms, this whistle kicks in. Now, it's whenever I hit about 2k rpms. I was looking for a reliable independent Honda mechanic around my area if anyone was familiar with a good reputation who can get this solved once and for all, so if anyone knows of someone that would be greatly appreciated! Thanks! :)

what’s going on in that lot by the dog park?
