Bmw of Honolulu is pretty mod compliant. I took my car in fbo(catless downpipe), with bootmod3 and some aftermarket coding. I would say as long as you have a good relationship with your service advisor and your mods don't directly cause the damage to the vehicle you should be fine. Theres always a risk you take though when modifying your car.
