This isn't exactly "tuning", but it is a mod. 
I installed a rack from a '15 Ltd. on my '16 PIU, but there were no crossbars. I don't actually remember ever seeing crossbars on one of these, but I've looked them up, and they exist. BB5Z7855100AA is supposed to fit '13-15, and GB5Z7855100AB is for '16-17. I can see some small differences in the pics, but what are the FUNCTIONAL differences? Any? None? After some searching on Amazon/eBay, it doesn't appear that the same aftermarket bars are offered for '15 and '16, so that suggests there IS some functional difference. But which bars would fit these '15 rails on my '16 roof?
