shhh noise as shifting

[donmia]

hello i have a 2000 nf350 drw .i keep hear a shh noise after it shifts will not go away until you let off the throttle a little if you give it gas again it does not come back.was thinking waste gate stuck.i do have a afe intake magnaflow 4" exh

[FORDBOY24]

prolly just the turbo..with a intake you can hear them decently

[donmia]

i always thought you would hear it more when you were getting on it not just cruising.but still learnig this

[KYcopespitter7.3]

look on your turbo there should be a plug for the turbo water level. i hear if its too low it can make a swooshing sound like when you hold a sea shell up to your ear. good luck tho

thats funny

[donmia]

found an old thread with same problem waste gate or ebv

[Strokeorcroak]

its backpressure.... the turbo looses boost when the truck shifts... That is what your hearing

[donmia]

yes figured that but just stays on when your on it gotta let off first just wanted to make sure normal my buddies truck is not like that

ebpv sticking is what it sounds like to me... what are the outside temps? below 45?
