Review on Universal Aluminum Manual Boost Controller: Efficient 30 PSI Closed-Loop Control Valve for Car Modification by Michael Tarlue

Works great but my app, Ecoboost f150, didn't like it. If you install it correctly, with a tee to both bypass valves, the ecu will see excess boost and still command the Bov to open, losing boost. If you bypass the bov electronics with 2 more tees they work but the ECU sees too much boost and goes into limp mode with an overboost code. The only real way to get more power is to get a tuner for it and preferably a special tune on top.
