[QUOTE="Bullitt5566, post: 15208376, member: 119066"] I have my IAC connected after the supercharger/aftercooler. I did this because I'm concerned the IAC may bleed boost at WOT and having the IAC inlet and outlet at the same pressure would fix this. I also know that the supercharger pressurizes the intake before the TB slightly at idle. I've run the IAC source both before and after the supercharger and didn't see a bit of difference. No surging. I think as long as the Idle Air values are correct it won't matter. The black box is a noise suppression device some ford engineer spent time designing it and I'm not smarter than a Ford engineer so I left it. [/QUOTE]
