Update:
I've removed most of my commentary in this thread because they painted Alpine in a less than positive way, and Alpine didn't cause this problem. I'll post a summary shortly after the resolution.
Original suggestion:
Those of you with superchargers should keep your old intake manifolds. Due to a problem with the shop that did the initial install of my supercharger, I'm in need of the block that the EGR valve mounts to. So save those old parts, you'll never know when they will come in handy.
