Help! Installed PS Boost Mod. - can't get over 20 PSI

Need some help here guys. Wanted to get the EGT down so I purchased a "used" PS Boost Module from a fellow and installed it. Before install, boost would not exceed 21. After install, boost remains the same. Placed 22 caliber shell casing in hard elbow and it is sealed. Boost mod is also installed. Pulled 17k 5'er and still no increase in boost.
Removed the boost elbow today to make sure it was sealed. While the elbow and diaphram were loose, I tried to move the rod back and forth that connects the boost gate to the diaphram - no movement at all. Can't believe the diaphram has the power to move the rod!
Have 275 injectors and VA Box. Took truck out at 50 MPH and floored it in overdrive. Boost bounced to 25 for a fraction of a second and immediately went back to 20.
Appreciate some help on where to go from here. Thanks in advance.
