You are saying "boost", but I think you mean "voltage" or perhaps "gain".
The Tekonsha Prodigy, P2, or P3 have a "boost" feature, which allows you to provide a certain amount of initial braking to "lead" the braking event, regardless of how much deceleration is detected.
The 25mph warm up stops for voltage adjustment is not done with the boost settings. It's done with the voltage/gain dial.
