State 2 bm3 reliability?
Considering voiding my 2020 m340s warranty and doing bm3 stage 2 with just the tune and a catted downpipe. How reliable will this be? Should I expect a lot more issues with the car anything major etc?
More frequent oil changes won’t be an issue |

Doing bootmod3 wont void your warranty.
run the recommended map for your mods and fuel and its highly unlikely you will have any issues. bm3 is reliable and safe as proven by hundreds of thousands of users currently running their maps.

A stage 2 tune from any of the major players will be just fine. Just plan on routing maintenance and enjoy the drive! Catted DP through the stock exhaust is a very nice setup too

Flash tuning your DME won't void warranty?

Don't take BM3, no after-sales service, one of my friends has his car going to a programmer because it always goes to safety, sends logs to bm3 and no response for several weeks, to flee, I regret having taken bm3 do not like me and go directly to MHD.

Nothing voids your warranty completely. But any damage caused by the aftermarket upgrade won't be fixed for free.
Example. If you flash your car and damage the DME. BMW will not replace it for free. But if you they will still cover all unrelated problems per your warranty.

I'll jump in here again, as ive said you'll be happy with any of the major (Mission, BM3, MHD, MG) tuners offerings. That said in my opinion they all have something a little different to offer and if you do your research you'll find your best fit. I'm presently running mission and couldn't be happier because they check all the boxes for me but we all are different. My point is contact all of them, do your research and the path forward should be clear
