Ford COP systems are like that. If there are no codes, slight misfire/surge issues can be difficult to trace. I’m sure the technician was as frustrated as you at not being able to pinpoint the problem. These are OE engineering issues usually, not a lack of effort or competence. I would suggest a throttle body cleaning and a careful mass air flow sensor cleaning. Next step might be a "smoke machine" test to look for intake manifold vacuum
leaks.

Automakers have turned to turbochargers and GDI to boost fuel economy and horsepower – with less displacement.
The popularity of turbocharged gasoline engines has surged over the past 20 years. According to the Department of Energy, approximately 1% of all 2000-model-year light-duty vehicles were turbocharged. Fast-forward to today, and more than one-third of all light-duty vehicles are turbocharged.
So, why the rapid change? That’s simple: fuel-economy standards. Current CAFE standards call for automakers to increase the average fuel economy of their lineups to 54.5 mpg by 2025. To meet these regulations, automakers have needed to innovate. This innovation has led to the advent of new technologies that have changed the entire industry.
