Turbo whistle different and louder

Hey now don't laugh, I'm sure there's someone somewhere missing a finger and on the phone with a lawyer.

 

And are you one of them
LMAO

 

Ha, I dump hot coffee on my crotch daily trying to sue for money. My lawyer told me I don't have a case since I make my coffee at home.

The devil is in the details!

 

Come to think about it my turbo whistle a different tune after Mr. Haney,s stage1.

Before it whistled "Swing Low, Sweet Chariot"...........
Now it whistles "Dixie".

 

That's because it's screaming for it's life. I've got 2 6nz's with stage 1 tunes and one is still running the factory charger. Not sure how it survives since the gauge stops at 35psi and it wraps clear back around to like 10psi on the other side and the wastegate is still functional. Everytime I ask the guy who drives it if he want's it turned back down I always get the same "deer in headlights" look. Funny how you think your truck runs good stock (which most 6nz's do) until you drive one that's been molested. Same with my Acert, always pulled pretty good but after the flash it doesn't even idle the same.

 

Eddy: With 600 HP you may not notice a HP loss but the condition you speak of may be caused by a Intake clamp not torqued to spec. The spec is 90-110 inch pounds. Not Ft LBS. anything less will allow the turbo boost to leak out under a pull. Another sign of losing boost from a loose intake clamp is a black trail os soot where the pipe is leaking.

 

07-397Pete: The reason you gage shows 35 and is maxed is because of the type of gage. If you were using a water manometer type gage it would show about 70 lbs. Most of the oEM Turbo gages are about 50% of the realtime pressure reading.

 

My gauge aint showing 35psi. Mine shows 53~55psi.

 

Do you happen to have turbos for a 2008 Freightliner Columbia detroit 60 series turbo. I also have the same whistle problem like the person mentioned. Not sure if it could be the turbo actuator either so who knows at this point.
