Weird.

I always thought the T in any of the numerical variants (2.0T, 3.0T, etc.) stood for turbo.

Last week I bought a brand new 2019 Mustang GT with a Roush supercharger installed by the dealer. Today I took it to a shop and put it on a dyno, and it only put out 380hp and 335lb/ft torque at the wheel on a Land and Sea dyno. The dealer told me there is a "break in period" programmed into the computer, so the car will not output full power until after 1500 miles. Has anyone bought a similar mustang before and experienced the same thing?

I think you need to find a Speed Shop/ Tuner who is more knowledgeable with the S550 Coyote platform. If possible of course.
