Squealing Noise from EFI mustang HELP

Problem Fixed Thanks Jameser. Problem was vacuum leak in between upper and lower. Word of advice to anyone who has a system Max II intake DO NOT USE O' REILLY'S gaskets for a truck lower. Yes similar design but the gasket will not line up right and you will have the same problem i had. Thanks everyone for the input. Also I have to say I have posted this problem on YB and corral lots of views maybe 1 or 2 posts but noting near activity of Motown muscle thanks y'all
