I have an 05 lly and I was going down the highway and I was in the process of passing a slower car when my truck started to build boost it cut out like I let out of the throttle and now it will not build boost at all when I hit the throttle its like the truck goes in to a limp mode there is no check engine light and I have no clue what to look for any help will amazing also there is no programer the truck is stock

Is it blowing an unusual amount of black smoke? Maybe look for an air leak somewhere on the intercooler boots.

Yeah it started blowing alot today I was wondering why it was doing that so it sounds like a leak in the intercooler boots

That would be one of the first things I would look at. OkOk guys...I have to say it.....make sure fuel filter is good also. A fresh filter actually DOES do wonders...especially when no aftermarket fuel system is used. (meaning no extra filtration before the factory filter)
