Its from Crane Cams electronics. Its basically a progressive controller that controls the amount of nitrous flow with RPM instead of time. I am not sure if these have been out for a while but I have been looking for an RPM based controller for a while now. This may not be ideal for the strip but will be good for the street and save wear and tear on the motor since it will not see that huge Tq spike down low in the RPM range. It should mimic more closely an NA powerband. Relatively cheap at $260 I believe.
