how to increase HP on an ecoboost vehicle

Our shop has far fewer internal engine issues with the 3.5 of all generations than the 5.0. Lots of knocking, ticking, valve dropping, oil useage issues, out of round holes, and recessed valves with the 5.0. 

Boost used to be hard on stuff in the old days, but it just isn't as detrimental to long life now.  

Same experience here. 2011-2014 5.0 seem to be less troublesome than the 15+. I recall 4 ecoboost 3.5 with catastrophic failure.
