  1. 6.7 Performance Parts Discussion (2011-2016)
    Hey guys I have a 2016 F250 Lariat 4x4. I just did the DPF delete but still have the stock exhaust muffler and tip. I really wanted to get the Turbo whistle, whoosh, (waste gate sound) from deleting the exhaust like you hear on the older 6.7 like the 2011-2014. I have looked all over youtube and...
  2. 6.0 Motor problems
    I've got an 06 6.0 and I've noticed for a few thousand miles that when my truck warms up, it makes this weird whistle noise off acceleration and on idle. It sounds like air puffing but I'm not sure what it can be. You can hear it on the rear of the motor but also sounds like it's coming from the...
  3. 6.0 Motor problems
    I've got an 06 6.0 that makes this weird whistle noise after it gets to normal operating temps. You can hear it when you de-accelerate and on idle. It doesn't sound like the failing roller lifter issue it sounds more like an air whistle. I can hear it from under the truck too. I'm so lost on...
  4. 6.0L Problems Forum
    Hello fellow strokers, So I am having issues diagnosing a funny noise coming from the turbo area of my 2005. Just wrapping up a Asheville Engines Performance 30 Coated Longblock install with a turbo rebuild and Batmowheel install and I have a whirring sort of noise. Here it is... Any...
  5. 6.0 Motor problems
    I've got a 2006 f250 it's got 221k miles original*turbo. Predator programmer. 4 to 5 inch straight pipe. The other day I drove truck and I heard the*turbo*whistling extremely loud, but only under the hood and under acceleration over 1000 rpm. The exhaust sounds as usual but in the cab and under...

    Well I absolutely love hearing my turbo spool up, is there anything i can do or get to make the whistle more prevalent?
  7. 6.0 Motor problems
    I installed a new powermax today on my 2003 F250 6.0 @ 164,500 miles. I was expecting to hear the whistle like in the stock turbo but there's no whistle at all :( Do I need custom tunes to get the whistle back? I still have the stock exhaust on it, not sure if this makes a big difference...
  8. General Diesel Discussion
    Has anyone ever had a noise that sounds like a freaking Harmonica?? Ok seriously- I just rebuilt my turbo because I THOUGHT it was impeller rubbing. Nope. At least I only wasted $100. However, the real reason I did it was because as my truck comes on boost, it sounds like it makes a harmonica...
  9. Diesel Diagnostics
    For the past 2 weeks I have been hearing a high pitch whistle about 2 seconds after I start the engine and it only lasts for like 2 seconds. It doesn't sound like a squeaky belt, but I am no mechanic. I live in So Cal so its not like its cold outside when I start it up. It doesn't feel like the...
  10. General 6.0L Discussion
    I've watched 100's of turbo whistle vids on YouTube.... My question is how do I get the loudest sound I can get get? Exhaust-Straight pipes 5" to stacks or out the back(single, duals)? Tuner- manipulating the VGT?? and anything else I guess, defineitly saving for a Powermax but in the mean...
