Can somebody help me I have a 07 Dodge Ram 3500 mega cab dually 6.7 that out of know where has started boosting high. I pull cars on a single car trailer and with car on trailer on straight away I would normally boost around 3-4 now I’m boosting at 11-12 and up hill it will boost all the way to 30 it never would get that high 23 at the most with heavy car on and going up big hill. I have checked I’ll houses to inner cooler and cleaned all Sensors and checked the fans on turbo. All I can hear in cab of chuck is a hole bunch air that drowns out my turbo. I’m at a loss

 

Does the exhaust brake still work and if so, has the boost reading changed when it's engaged?

 

Yes exhaust break still works no change when it’s on

 

Is your vehicle 100% stock or modified with a Programmer and some deletes?

 

Deleted with H&S tuner has ran great for 3 years with no problems I always keep it on tow mode. I’m never hard on truck baby it even when pulling. It Seems like it is getting worse trans shifts fine not sleeping just boosting way more than normal I drive truck every day pulling car.

 

Do you use the exhaust brake religiously as well as tow haul mode? Sounds like you may have a dirty turbo...
