Dealer Cleared JB4 tune? Newbie Questions ab it

Hey everyone, newbie here to the F10 Scene, but not to BMW. Bought my 2013 535i 2 weeks ago with a JB4 and Burger intake. Love it, car really comes alive when you put it in sport mode and the tune kicks in.

So i took the car to the dealership for an oil change, left the JB4 in didnt do anything to it, rolled the dice. Dealer changed the oil, replaced wipers blah blah blah.
Never said anything ab the tune, even ordered me a new radio b/c the plastic was peeling and key b/c its not working correctly to be fixed new week. So it was a normal dealership experience

Driving home i noticed no difference when i put it in sport mode (other than a little throttle response). It feels like the tune is gone? When i would put it in sport mode before i could feel it kick in immediately.

Could they have cleared it out? Also since i didnt install it the previous owner did, do i need to download any software? Or can i just hook up my mac or any PC to that JB4 black box via the USB cable and turn the tune back on?

If so how?

Thanks for any help!

Dont have any good pics of the car, but here is one from when i picked her up and my E46 M3 that i sold before this car.
