I have the same issue with my 12 Ram 2500 CTD. Can't get the brakes to lock when testing at 25mph. Even on 10. However when I have had to do a panic stop they will lock. It's like there's no middle ground. I had the issue brand new. Ram replaced the OEM TBC with another one but no difference. I didn't like the OEM TBC as I just didn't feel comfortable with the way it worked. So I bought a Tekonsha Primus IQ. I can lock the brakes easily with it. I set the gain to 5 and the boost on 2 for hwy and 1 for town.
JMO but I think the boost sensitivity is off on the Ram TBC.
I know the Rams not right as I towed a previous TT with an F150 with an OEM TBC and it worked flawlessly. Then when I got the Ram it was like the same TT's brakes went bad over night. That goodness for the Rams exhaust brake.
Also have tried setting the OEM on either heavy or light and there's no difference in how they react. On heavy you can feel it drag more but it's still not right.
