I just out a JLT RAI on my car about a week ago. I already have an IAC restrictor plate. I have noticed that my rpm's are hanging more since the CAI install. It is not as bad as stock without the IAC plate. I think the CAI introduces more air and therefore the rpm's hang more.

Gunny, the hissing sound is air being sucked into the filter. I love that sucking noise when you blip the htrottle with a CAI installed.
