I have a 2015 6.7 platinum and whenever I am towing it keeps throwing turbo boost sensor circuit high and goes into limp mode. I reset the code and it runs fine. The truck has a sct on it set on the tow tune but even on the stock program it still does the same thing. Do I just need a boost fooler or do I have a bigger issue?
 
Figured I'd post an update since no one knew a fix and this is a common issue on 2015-16 trucks. Turns out there's a tsb to reflash the computer to fix it.
