Brad, I would suggest that your tag doesn't have enough weight for the amount of brake air it's getting. I have a
similar setup and there is about half as much weight on the tag as the drive axle. Ours is in the paint shop 200 miles away so I can't get the last weights, but if everything else checks out the tag should probably be carrying more load. Our MCI did this when the proportioning valve was bad. We had 20k on the drive and 4.6k ish on the tag. Now there is 17k and 8 k. All good now. I think our Newell is heavier, but the ratio should be similar. I would think 20k on a tandem dual axle would be max with 11" tires
