Anyone Replaced The Integrated Brake Controller?

I replaced the IBC in my 12 Ram 2500 with a Primus IQ. The Ram IBC is too jerky at stop lights or when cruising thru a campground. The IQ is way smoother.

FWIW I'm on my 2nd IBC. The 1st one was bad from the get go with less than 1000 miles on it.

Previous truck was a 2010 F150. The IBC in it was the best BC I've ever used. Ford seems to have it dialed in better than Ram IMO.
