. I can lock up the wheels so that it jumps around like crazy if I manually use the controler. My controler goes up to 12 with 10 decimals between each. If I crank it to 12 it locks up manually. If I put the controler to 6 (what the manufacturer recommends to start) it does not lock up using the brake pedal. The problem is picking the correct setting for your trailer. I finally had to use the boost to get the setting I like. (I have 3 boost settings that seem to give a bit more brake) I think there is more than enough stopping power in the 7" brakes. I think you just have to set them up correctly.
The purpose of the 'boost' setting on a prodigy is to make the controller "ramp up the braking power" more quickly when you first apply the tow vehicles brake pedal. It does not change the total amount of braking being applied.
In other words, with no boost set, when you touch the brakes on your tow vehicle, the trailer brakes essentially come on gradually. When you set the boost let's say to "1", as soon as you touch the brake pedal, you immediately start getting 13% of what the total braking is going to be ( but the same maximum ). At boost 2, you start with 25% of the total braking.
You may find that if you set the boost too high, it can make the brakes feel kind of "juddery" ( technical term ! ) around town at slow speeds. So sometimes I punch mine back to "no boost" when going thru stop and go traffic, and then punch it back up to B1 one I clear out of town.
