The EMS controls boost settings per tuned rpm, and gear. Just wire it to a quality boost solenoid of your choice, and it will control it according to your inputs. Pretty cool if you ask me. Just takes a lot of fine tuning.
I am going to see about making a 3 way adjustable knob to toggle between "Street", "track" and "race" Boost maps. Got the idea from that new Noble on Top Gear :)
