There are two adjustments on the P3- boost and braking power(voltage). They are not the same. Did you or someone turn the braking power down?

Actually moving and stopping the unit will apply more voltage based on how hard you are braking the vehicle.
The way I adjust my P3 is to first make sure the trailer brakes are adjusted properly, then turn off the boost function and adjust the voltage until I get enough braking power so that it stops well and doesn't lurch, but I can still feel that I apply more pedal with the trailer than without. Then I turn the boost function up until for most stopping situations I can't feel the trailer.
