Anyone else that has a CAI noticed a noise at low rpm around 1500-2500, in 5th gear? It happens when ya give er some gas to accel a lil bit, but not enough to downshift or get rpm above 2500. kinda sounds like valvetrain noise thats backfeedingthrough the intake. never had it before the intake was installed and it seems more common after the truck has warmed up some. i'm kinda convinced it's valvetrain noise thats being backfed but, just curious as if anyone has this noise.

 

you might be surprised the amount of noise the OEM resonator hat supresses.
it's prolly nothing new... just something not being muffled any longer.
