Our maps will build more boost, quicker, in general. You'll need an AP to see what rom you have, so you'll know when you install for the first time, or if you have a friend with an AP, you could have them uninstall and let you try it so that you can see ahead of time.
98G0B was an update from BMW and the overall power delivery isn't all that different in my opinion, but it definitely feels smoother to me. In general, I always encourage customers to get the most recent update from BMW. They wouldn't spend the time to release something for no reason. If there's ever a power decrease from them, our mapping should get you extremely similar power regardless of which rom revision you have.
