I recently installed a 5 star 87 octane P/T tune in my truck ('16 3.5L EB). Truck runs great, shifts nicely, and is overall much more pleasant to drive. I haven't noticed anything concerning, no knock (etc)......although, in general don't drive it very hard. I occasionally tow a 7k enclosed car trailer.

Should I be data logging and submitting the information back to 5* to be safe, or am I good to go?

Thanks

It's always a good idea to at least datalog once for them to review, but if you're happy and knock looks good then it's not a real big deal.

And don't feel rushed to get a log to them, you could even get one the next time you tow just for them to check it over .
