Intake Hum Following install
So I just finished up installing my MS-1 I purchased from another member here, did the MAF deletion and all that stuff. Now I have this ( for lack of a better term) hum coming from my intake. Its loud enough that is hurts your ears and occurs at idle the loudest but dissipates the hight the RPMs are. I did figure out it is coming from the Idle air control unit and is magnified by the intake pipe ( Old school Rspeed intake). I am running the base map provided on the DIYautotune site until this weekend when I have a chance to actually do a bit of adjusting on the Dyno. had anyone ever experienced this before and is there a fix? BTW its a 1994 1.8 with header, intake and full exhaust. I am running tunerstudio if that matters.

That was the first thing I check was all the hardware and misc stuff I had fiddled with. I am 100% sure its the IAC valve, I actually pulled it from the intake pipe and the sound became much more bearable ( intake was acting like a megaphone), but the noise is still present.
