You can read boost up to 14.7psi on the stock gtp pcm/map. It will read out on a scan guage or an aeroforce guage as I have one. As far as logging it, you may have to make a .pid and convert the map kpa values to boost.

As far as hptuners standard version I thought you could wire in the wideband signal through the egr and create a .pid to be able to log wideband values without having the a/d inputs.
