I installed it about two weeks ago. And truck runs bad to the bone. Was coming home from Dallas sunday pulling my trailer. The truck ran great all the way into my drive way. After I unhooked my trailer and took off. Truck had no power when I hit the gas pedel and I was hearing a horriable howling sound. I pulled over and turn it back to the stock mode. And howling sound went away. Today I put it back on 75 HP and there was no howling sound it just felt like there was no power.. any ideas? I might take chip out today and reinstall it. Any info would be awesome. Thanks Jason P.

 

Id try taking it out and making sure the contacts are clean with no silicone on it.

Well turns out it was a hose clamp that came off the bottom side of the turbo that gose to the valve cover. Bitch runs good again. ;-)

 

Huh? The intake side of the turbo? The Crank Case Vent?

Thats the only thing I can think of that goes to the valve cover...

It's a rubber hose with two hose clamps on it. Maybe it wasn't going to valve cover but it was lose and it fixxed my problem..

 

how big of hose?

 

It.looks like a 3" hose by 4" long two hose clamps top and bottom. Top one was real lose. Tighten it and truck ran good again.

 

that's the intake tube...

 

o ok. well it has to be tight thats for sure. or it will make a howling noise.

 

that's the turbo whistle you heard.
