Detroit S60 low turbo boost

Yes i think so I have seen the same thing when guy's would put resistors on the boost sensor and the connection corroded. Clean the connection and truck is back to normal. So in your case i would check the connection and the ecm grounds and if you can plug in and look at the output reading of the boost sensor and see if it looks normal or not. Your on the rite track let us know what you find.

 

Hey Aussie Dave.
when u check the cac, Disconect it right off the hot side of the turbo and don't cap off the cold side. This will check the intake manifold gask. and the air compressor intake hose.
You can also use a prolink while , Let's say adding 20psi to the tester and monitor your turbo boost sensor to see if the boost sensor is reading properly.

Good luck

 

I had a similar problem and it ended up being the exhaust side blades had shattered from a piece of the turbo casting while the other side looked just fine. Do you get more boost at higher rpm's, if so this could be your problem. I'd think you could hear a bad air compressor hose, at least I can anyway.

 

Spray all your fittings with a soap and idle the truck up to 1000.

Found lots of leaks that way.

 

Its a non EGR which means it most likely doesn't have a VNT turbo so it won't build boost without a load on the engine like a EGR engine will

 

Understood.

I'd still suggest it

 

Looks like your on the rite track!!!!!

 

I have done this also, on non EGR motors, works every time. Rarely did I NOT find a small leak of some sort.
