prodigy brake control
I have to concur with Gary B, I just set mine up per the instructions, I then after driving with it backed the boost off some. If going down a long steep grade I will bring it up a little but that's about it. Under normal driving conditions I like equal brake power between the trailer & the tow vehicle. For what it's worth, the money i spent on my prodigy is the best money I've spent, I love this thing !
