Tried using the search feature and that was not showing anything. I changed out the PCM to an Arrow on my Gen IV and it made that car a completely different car. Throttle response improved immensely and the car felt more free flowing (that is the only way to describe it). The Gen V feels restricted when getting on the throttle when compared to the Gen IV...so what does the Gen V Arrow PCM do to the car other than allow for certain mods?
