VGT duty cycle & eletrical ??'s

Well I have a problem with my truck building boost. It was a problem since I had it thought it was other problems but still there.

First I did put a new stage one turbo on it and it did have a new seloniod on it so I doubt its the selonoid. Did the same thing as the old one. Had the scanner on it and at a cruise 55-60mph it's at 30-35% duty. even wide open its at 45-50% and boost is just not there 0 psi at a 55-60 15-18psi at WOT

If i unplug the Mass air sensor It will run upto 85% duty cycle on the VGT selonoid. I also Unpluged the MAP sensor and it came up to 50-60% duty. If I unplug the EBP It does nothing runs the same. Any help would be helpful. Also when we had the scanner hooked up we could not find the EBP on it does ford call it something else. Its a snap on solarus.

The Veference volts was also low 3.5 but at the MAS its 5.1 volts at max. which is weird also cause with ID tunes on it it will max out the MAS volts at 5.1 at 3/4 throttle. So the sensor is telling me its maxed out.

With the tunes on it it has better boost response but still not very fast and no boost at a Cruise.

Sorry for the long post just trying to figure it out
