I wonder if BD module is the same as DD's?? With basically stock HP, I tried both the DD and Practical Solutions boost module/elbow. The DD gave 30psi boost with stock injectors but the engine was a dog, it was damping down the signal too much across the boost level spectrum. The PS module works MUCH better on non-BOMBed or RV-injectored trucks, since it allows the MAP to see normal boost until reaching max psi then caps it there.
