Nope, if I had wanted to say peak torque, or meant to say peak torque, I would have said peak torque.
On cam also applies to every engine with a camshaft, turbo or not, diesel or not.
In the graph above 4000 rpm is
well below peak torque, but it is
still very much on cam, and will stay that way until the valves bounce or it can't suck enough charge air in any more.
