I think you missed the point, if you were serious. Yes, I did notice the smiley. The problem with standard RST setup is that when you are pressing throttle (+1bar in manifold) you get no servo assistance at all and you must press brake like hell for any effect. Then, when you back the throttle a bit, the servo kicks in and the car brakes like hell suddenly.
I'd like the car to brake the same, whatever the manifold pressure was. Cossie "servo" can be one solution as it doesn't rely on vacuum to boost the brakes, but stored overpressure that a small electric pump creates.
Alternatively one could install a separate vacuum pump and keep the std. servo.
