My '08 GMC IBC is set at 7 and the new fiver stops great. My old fiver I had the IBC maxed out. Remember these don't have the same stopping feeling as the after market do. These are designed to feel as one whole unit and you won't generally feel the trailer grab. Make sure you are in tow haul mode and you will use a lot less brakes as the Allison is awesome at slowing the rig down. Take it out, get up to speed and try some hard braking to get the feel on how it works. I love the IBC on the new trucks.
It does seem to work but if it's not suppose to grab like the aftermarket stuff then it might be ok. I just don't like it maxed out and I haven't loaded anything in the camper including water!! I'm going to try to tighten the brakes up at each wheel, I have been told to tighten then then just back off till the wheel turns freely, not 8 clicks. I'll give that a try. I have also been told that the brake controller is "adaptive" and will have to be backed off later as it will get better, any truth to this??.....
I adjusted my brakes on my old fiver and really didn't notice much of difference, I later found out it had smaller axles and brakes than my new one. My dealer adjusted the brakes on my new fiver before we left the lot. When I pulled out I had the IBC set to ten and locked the brakes up at the first stop sign. I was amazed at the difference between the two trailers. I will adjust my brakes again after my next trip in June to make sure they are set properly after the good break in period.
Not sure about the adaptive learning. It will take a few trips to get.comfortable on how they feel and you'll love it.
