Default Where's my boost?

Just did a swap on my 07 nnbs Sierra from 4.3 to 6.0 with tvs 2300. Had the shop install a new auto meter cobalt digital gauge. The problem can't get it to read positive boost only shows negative.

You have to connect the reference to the boost gauge to somewhere under the rotors of the blower.
