I have set the P3 to 7.5 and the boost to 2 and the type to Electric. When I step on the brake, the TT brakes barely engage.
Manually applying the trailer brakes causes the TT brakes to engage, but the do little to stop the truck an trailer. I had the TT brakes adjusted by a pro at the local RV dealer. Under the old Tekonsha Envoy controller, I could apply the TT brakes manually and lock them up.
I had (sort of) the same issue with the same controller. I also found that the P3 is not a 'set it and forget it' controller. Mine will lock up the wheels at in town speeds and seem to have little braking at highway speeds if not adjusted for conditons. As a start go higher on the voltage and boost and then back it down to where you are comfortable. After I began to understand the controller I now have the brakes where I want them both in town and on the highway but it does require a re-adjust on the boost. If you don't think the controller is working properly tow a different trailer and see how that works.
