My 08 with 118K has a rpm based noise that sounds like it has a loud supercharger. seems to be coming from the turbos....which have been replaced 10K ago.
It sounds nice lol..but i dont thing its normal. is at its loudest when i push the throttle 75%...and with 20-30lbs of boost.
The truck drives absolutely fine.

i know what your talking about. pretty sure thats normal. or atleast every 6.4 i have rode in has done it

Does it make the noise when your getting on the throttle and you can hear it again when you let off? Almost like a whine? I just bought a 2010 6.4 and have the same issue interested to see what everyone thinks.

Guys, when the boost goes up, its a VERY loud whine. i took it to my diesel mechanic that replaced the turbos, and he said its possible i have a leak..

if it didnt do it before but it does now then its not normal. could be up pipe leake (im just guessing) check for black soot behind the turbos
