Normal sound?
I have a 6.0 question.
After backing off the throttle fast, I sometimes hear what sounds like a gradual backfire in the exhaust manifold (drivers side), it's not a loud bang or a pop. The truck runs great, 3,200 smile miles for far. I've been getting 17-18 MPG with 50/50 in-town/hwy miles.
Is this a normal sound after backing off the pedal fast?
11/04 truck build date, the label on the engine has a white bar code label which shows 6167417-EG042AB. I'm not sure where it was built or how to decode the engine serial number. VIN 1FTNW20P94EB07408 2004 F250 CC 2X4

Yeah...
Nice job Tim!!
TURBO BARK.. Normal.. Even the 05's do it.. If you power brake, and bring the RPM's up to 18-2000 (sometimes lower) and snap the throttle closed, you'll hear the 'Tim' sound!!!

I feel much better now that I know it's a normal sound.
How do you spell the whistle sound?
Thanks!

so nowhere for the substantial turbo boost it's built up to go when the throttle is chopped is except back out the least resistance - the intake....
Wanna fix it ?
Don't slow down - just run em over if they stop on YOUR road
