On previous vehicles, that's what I did. But those were super easy plug and play OBD II tuners. Plus I hardly ever had to go to the dealer anyway.
With BMWs, you get free service (which I will be taking advantage of), so I will be visiting a dealer at least every 5,000 miles. And the JB4 on my 335i takes quite a bit of time to remove and install, definitely not worth the hassle of always having to do that. So many plastics underneath the hood, and they all get brittle and break over time as the car ages if you keep removing them.
