Chops from far forward on the loin where the muscle dives into the shoulder can be tougher, or far in the back where the sirloin marries to the loin, but it sounds like you have a good cut of chop, that shouldn't be a problem. In my experience, I will not age pork the way beef is aged- pork is a very touchy meat as far as how it reacts to bacteria, it will go over much faster then a beef carcass will. In a perfect world, I'll hang a pork 24 hours to get it chilled through, then it goes onto the block. They can be hung up to a week, but much more then that and it risks getting slimy. I don't know industry standards across the US, much less in Europe, but I'm willing to bet pork is rarely aged. In smaller shops I can't say, but I haven't seen much about aging pork to improve it. If I'm wrong there, I'd appreciate being pointed in a direction of something to read, I enjoy learning anything I can about the entire meat universe.
The temperature is a smidge lower then I cook, but I cook for resale so I have to be a little less flexible. I take smoked loins & hams to 144-146, but that's a fully cooked level. You're definitely not overcooking.
It sounds like you did everything right from start to finish, so it may be just one of those things. Maybe the hog had a backache the day it got slaughtered, who knows. Sometimes even when everything is done perfectly, it fails. If it's a constant issue, try taking a chop and just cooking it like a fresh pork chop for dinner and see how it reacts. If it's tough both ways, then you know it's the meat and not the process. If it's the process, try changing brine recipes or making it yourself- maybe the brine manufacturer got bought out or changed their process somehow.
