I just installed a p2 in my truck and while adjusting I had at one time the controller turned all the way up and the trailer brakes won't lock up. I adjusted it and feels great stopping now Compared to the previous controller that was not proportional. Is it a problem that the trailer brakes would not grab hard enough to lockup? I will say when I hit the manual lever it snatched the truck pretty hard.
