Detroit 60 series 14L low power.

We just purchased a 2005 Century Class with a 14L 515hp Detroit s60 series engine, 10 spd trans, 3:50 gears and 22.5 low pro tires. This used to be a JB Hunt truck.
This truck has no power at all. I drove it today, the only thing slower then me was a 5 axel garbage truck. Once you hit over 1600Rpm no power at all.
Also while cruising with the pedal to the floor I keep hearing a squeaking noise coming from the right side of the engine. As soon as I release the pressure even so slightly the noise goes away. Step on the pedal I can hear the turbo spooling up and it cuts off and the noise is back. Anyone have any ideas.

 

Anyone? No matter how silly the suggestion.

 

I'm going in next week for a print out. I believe the parameters are on the weak side, well I hope they are.

 

Update.


Freightliner opened up all the parameters and she pulls hard through all RPM's. Jb Hunt runs their trucks @375 Hp. Poor drivers with those 80,000 lbs loads.

 

That one we have not figured out.
