[mjX3]

I currently own a 2019 X3 M40i and have long thought about a tune for my B58. I will say that I do not plan on any other mods beyond a tune. No intake, downpipe, etc... I know BM3 appears to be the most popular tune thus far. For those who have gotten the stage 1 tune:

1. How is the power delivery?
2. Does it create any jerkiness with the transmission?
3. How you found stage 1 to be enough or have you upgraded to stage 2?
4. Is it noticeable on the "butt" dyno?

I know tunes have been beaten to death on here and I have searched, but there are simply too many threads anymore.


I appreciate any input. Thanks guys!
Matt
