No boost after GP, GPrelay and GP harness change out

I have no turbo boost after GP, GP relay and GP harness change out. After the GP work was completed, I had an engine lite, I disconnected the batteries for 30 minutes and reconnected for a putr reset. I had no boost before and after the putr reset.
On the highway the truck is slugish and with my foot in it, it may boost up to 3-5 psi.
Any Ideas?
2005 6.0L SD King Ranch stock as ar as I know.

No Boost issue partially solved

No Boost issue partially solved but still need help. Truck threw P2262 code Turbo Boost Pressure not detected. I started checking connections thinking I knocked a connection loos and found the the MAP sensor has no vacuum hose connected to it and I cannot find the hose to reconnect it. Does anyone know where the vacuum line comes from for the MAP sensor?

No boost prob solved

OK I figured it out! During the valve cover gasket change out on the passenger side in never reconnected the MAP sensor hose. Finally found the hose hung up under the firewall.
Back in the saddle again!
Nothin like answering your questions!

Intercooler pipe blowing off

Didn't want to start another thread but.... I have replaced both intercooler hoses on the input side of intercooler, roughed up surface on the aluminum tube, even over tightened all clamps, but i cannot keep the tube in tact at WOT. This is pretty much a stock 6.0L 2005. This problem started after a glow plug, harness and GP relay change out. I dont see the relation, and still having a minor starting problem. HELP from all input is appreciated. I will add that the exhaust is completely free flowing, no CAT. Some people say that it is chipped but I cant find a reason to support that. I have done 2 computer resets via battery disconnect for 30 minutes. I do not have a programmer at this time.
