Im having this issue were my truck is making a vacuum sound when i accelerat, i have had this sound ever since iv had the truck but when i started it it would make the sound for about 10 seconds and cut out then it would spool and make that beautiful whistle sound, my problem is this sucking vacuum sound doesnt go away anymore and it sounds like carp. Anyone know anything??

sounds like your ebpv is partially stuck shut. have you noticed a lack of power when it does it?

vacuum sound

The Ebpv is on the outlet of the turbo exhaust side. Has a rod that runs from it to the pedestal. Should be all the way towards turbo to be open

on the drivers side of the turbo pedistal you will see a 2 wire plug un plug it and it will not activate again. just make sure it is open when you do it and i would wire the rod open so it can't close again
