Taking the rack limiter will not net 40hp. Adjusting torque control and max speed settings in your pump governor just might. After that, a small rack adjustment will be all you need to make your 617 perform as best as it will. As stated earlier, you can find a detailed write up on RW governor settings at the STD forum.

As opposed to cutting DVs or turning elements, these mods will leave your car idling right and not smoking like a chimney.
