I’ve been running the Whipple kit for 8k miles with no issues. The difference in power and throttle response is very noticeable, and I am happy with my trucks performance. However, I do not like not being able to revert to a stock tune should an issue arise, and that even if you are able to get a stock tune from Whipple (which takes months from what I read on here) it will stick out like a sore thumb to Ford and they may not flash any of your components ever again. In summary, the Whipple kit has been amazing, BUT unlike advertised, it may be the “unfriendliest” Ford tune out there.
