Since the 35i is my first car with a turbo is it bad for the turbocharger to engine brake? I notice that when I downshift around the 2k-ish range and it revs up to around 3k rpm the car actually speeds up a bit because the turbo spools up so I in turn have to brake harder or downshift again and rev the engine higher than 3k rpm for a larger engine braking effect.

All of my previous cars had NA engines and I've never experienced this issue so I'm not sure if the problem arises from having a turbocharger or if it's from the X3/8-speed.
