Go take your truck for a drive, and see if it moves. Get on it pretty hard and load the engine down. It will not move at idle, because there is no load on the engine. You gotta put some strain on the engine to produce boost. It's mechanical, so you don't need electric to make it work, so go try it out now.

Nope, revving it in idle puts no load under the engine.

29 is good. If I remember correctly 23 is what the truck is set to defuel at and set a code. Do you have a boost regulator for your map sensor?
