Why does my diesel engine whistle when I put my foot down?

No, since a) diesels don’t have throttles, so keep pumping air through without any fuel, and b) most modern turbos have variable vanes so they can keep spinning without pumping much air (and thus don’t need to spin up much again when you put your foot back down, reducing turbo lag). Start worrying when it stops whistling.
