Go get a new throttle blade from a junkyard and have the tune made right, not band-aided like ZZP did to you.

Not sure how many times I gotta tell you this...

Then why does it entirely go away with the belt off the supercharger? And the noise isnt coming from near the throttle body at all either.

Maybe get a different power adder.

Roots blowers aren't quiet...but they aren't as loud as centrifugal ones.

I suggest a stock airbox for you then.

Yeah I dunno mine sounds diff than yours but similar... I like the whine during higher throttle just not the whistley idle thing/low throttle thing lol.
