Low boost issue

Hey guys. I have a issue going on, I have an edge insight cts monitor, with no mechanical boost gauge but do have a pyro gauge tapped into manifold. I recently installed a stage 1 MTW turbo with the truck having no issues. Once installed, I actually paid attend to my gauges (I never look at them from day to day. ) anyway, I noticed my boost would struggle to read 10 psi. The egts were roughly 300 idle and 600-900 driving normal acceleration. I couldn't get them above 1200 and this is all with a 150 hp sct tune.I checked and found no boosts leaks. Even had a ford tech confirm no leak and normal running. Switched back to stock turbo (thinking it was MTW turbo w/ issue) but the numbers are pretty much the same, cant get past 8-9 psi but egts are similar, mind you the truck runs fine, pulled 8-9 k loader with no lack of power and same low boost reading. Also, get no dtc codes. I need help, have no clue where to go from here. Someone mentioned map sensor or ebp sensor?!? Does edge insight have issues reading boost without mechanical boost sensor, it used to work fine, got boost to 25-28 psi easy.My build date is 3/04. Thanks for any advice and anyone times
