Agree with others, think a misfire
As a min, suggest tuneup with new plugs & wires/ignition modules (all of them)
Assuming you were also running 91 octane
Also, have you flushed your coolant yet? 2016 so 6 years and is the coolant is at end of life.
Turbo creates tremendous amounts of heat. More so at full boost. With such a small block/heads, the surface area to reject that big block amount of air/fuel requires very good heat rejection system to get those higher BTU's per square inch surface area out
Ask the others who know more about boosted small engines if dropping down one plug heat range for towing heavy & into high boost a lot would help...but maybe down side would be non-towing, would the plug then foul more easily ?
