Geo Pro with P3 Brake controller?

[aboyz]

Hi,

I have a tacoma with the p3 brake controller with my Geo Pro 20bhs. I have adjusted it to 12.8 for my brake and I drive and test it out on a 25 miles and pull the p3 brake controller and it worked good.

My question is when I'm towing this trailer and I stop and go on slow traffic. It seem like there is a push on the stop and when I let go the gas there is a push to it. Like a jerk.
Is this normal? or is my setting on the brake controller is not set correctly?
