O.K.... I installed the fipk as well as moving the AIT and setting the TPS to .75 volts. This made such a difference with my other mods! The truck is much louder now, but at low rpms cruising through the neighborhood, i notice a whistle that i didnt hear before. Is this normal, or has someone else experienced this with the cai?

 

my CAI whistles like crazy...i tried changing the rubber fittings thatcame with it to greddy turbo fittings,. but it still whistles
