RE: Boost
I'm not 100% sure but when mine still had the mandate, I think it would hit 42 often.

My 2250 set at (500ST/1850trq) did as well, when it still had the mandate.

They also replace the turbo, and turbo actuator, egr cooler, egr valve. The engine run's very good. The only thing i am concerned about is is the turbo boost gauge goe's to 42. I have only allowed the boost to go this high a couple time's. It is my understanding the boost should only go to about 36. Also the best fuel mileage i can achieve is 6.0, and this is running the engine very easy, keeping the boost down to no more than 20. Also, all my regen are passive. Sure would appreciate some direction.


With that low fuel milage, even when running easy, what about a leak in the intake/ boost system?? That would cause over boost on the turbo as well as the low fuel milage.

RE: Boost
Got the hp turned back down to 450, and the boost max is now 36. Took it out on the highway, running about 63mph and the dash display showing 10.0 mpg bobtailing.

If you had a factory 600 program in a 450 engine, they are not compatible...

Along with clamp behind the doser, and several boots on exhaust and intake side. made it back to where i park truck, and did a forced regen.

I agree 100%. I was actually shocked when it was discovered.
