the vehicle needs to be moving to know which way to adjust and by how much.
dont overthink it, the manufacturer instructions should be pretty clear and to restate what i said in my first post...
1 hookup the trailer and have an uncrowded place where you can tow with it for a little bit without distraction or interruption as adjustments require moving the vehicle
2 i usually like to hookup and drive 500 or so feet with the boost lever pressed, this will make it feel like you are dragging the trailer or that the trailer brakes are applied too hard - but i do this to remove surface rust from the trailer brakes before starting any trips - you dont have to go all the way, use the lever to adjust the amount of drag short of lockup but hard enough that the brake shoes are scrubbing off that surface rust - again, a short distance is okay.. you dont need to grind them..
3 after completing step 2, use the dial to adjust the brake voltage setting, start somewhere in the middle and drive a little bit and apply your vehicle brakes as you drive and slow down and sense whether you think the trailer is pushing the car, the car is dragging the trailer or you are in perfect balance where the trailer brakes and the car brakes are applying the same amount of pressure
4 adjust the brake voltage dial up or down to achieve the balance, if it feels like the trailer is dragging your tow vehicle (like the trailer brakes are locked up too hard), then dial the voltage down so the trailer brakes arent applied as hard, if it feels like the vehicle is doing all the braking and the trailer isnt doing enough (like the trailer is freewheeling behind your tow vehicle and pushing it while trying to stop), adjust the voltage up to make the trailer brakes do more work.
5 there is no set number to use as every trailer, vehicle and their brake systems are variables. so you are tuning your trailer brakes to your specific vehicle.
6 the boost lever is used for instance in a panic stop or where you need to slow down quicker than usual and the pre-set adjustment isnt quite enough to keep the trailer from "pushing" your tow vehicle under those conditions - think of it like an emergency or helper brake. it should not be needed often, if it is, that means you need to adjust your brake voltage up a bit to make the brakes on the trailer apply a bit harder under normal driving conditions.
if you do a youtube search for adjusting prodigy p3 brake controller im sure you will find a lot of video examples which may be easier to understand.
its a very basic and simple mechanism and it will likely always require a bit of minor adjustment every time you use it - its not a scientific adjustment, its just an adjustment to how it "feels" when braking. get used to this.
i would tend to ignore what the dealer says - only because i think they tend to provide very general advice and do not take into account your vehicle, your experience, your comprehension and your needs. so dealer advise tends to be very rule of thumb. the P3 manual should have excellent instruction and like i said, youtube is probably full of great examples. do some research and learn some more about how the system works, what it does and how it does it and if you still have questions you can visit them here.
