The boost will indeed be variable, however, the best part is that no pulleys need to change, and unless you put your foot in it during an emisions inspection, your engine will be in a non boost mode and running naturally aspirated. We achieve stock and sometimes slightly better than the rules call for on emissions #'s in both drive cycle and static type inspection testing. For real performance up grades (race only) you'll be able to enrichen the mixture to optimum mixtures by simply flipping a switch and then turning a knob to the desired setting. No reprogramming and lap top tuning or even dyno time. We're building it so it's very "understandable", and although we are integrating some electronics with mechanical components, the system is dead nuts on in both accuracy and dependability.
