well for 1 the ford is a tune ,not a piggyback, 2- the ford has a transmission tune which is great , 3 u lose nothing as far as down low torque ,the jb4 u lose a good amount down low and gain it up top. the ford numbers may sound low, but u gain across the whole band ,the jb 4 u do not .Care to elaborate on how it’s better?
