Turbo Diesels can’t be compared to modern turbo gassers - they generate power completely differently, and feel completely different.Turbos are not all they are cracked up to be. Had a 2017 6.7 turbo diesel F250, the holy grail of torque. Nobody likes to admit it, but turbo lag never went away folks. Very annoying when in heavy traffic. You floor it and then wait. Bye bye open space in traffic and hello late rush of power you no longer need.
Also, that powerstoke is bogged down by so many emissions and economy add-ons, and the throttle response you’re interpreting as ‘turbo lag’ is there to use less fuel. A simple flash will wake it right the heck up, heck I can break my 35s loose at 3/4 throttle and I’ve only got the 6.0.
