I have a 2005 LLY. Running a power pup to correct speedo for 285 tires, and a juice/attitude for power upgrades. I have a 4 in exhaust with cat removed.

Anyway I keep getting a SES light. IT comes up DTC 0299 on the power pup. I have been told it is related to low boost sensor? did a quick check on intercooler hoses and don't see anything loose.

If I am driving the truck idown the road it doesn't seem to set a code. It seems to occur when idleing or slow movement like backing a trailer into the garage.

I know its under warranty but I was hoping I could fix the problem without removing all my mods and returning it to the dealer........ any ideas would be great.

Low boost code.

I have one in now with that and a p0045 stored...runs like chit...

Diagnosis... cust filled truck with gas

I didn't put gas in it. I have owned diesel for 6 years and never done that one.
what does it mean to have a p0045 stored.... whats that one?

p0045 is a turbo charger vane position actuator

guess I'll take my stuff off and send it back
