If you're not familiar with the generic E9x tunes, they traditionally* increase the governed speed and increase third-gear redline by 100-200rpms.
According to the dealers evidence from BMW NA, I got in the habit of using the last 100rpms, 1500 times.
The shop-forman who I was on good terms with suggested I come pickup the vehicle before it's warranty red-flagged.
Now that you're all familiar with my story on a previous gen BMW with less computer logging and engine management than the new and current gen cars would you still tune your beast?

I was heavily modified and never had an issue. Bmw was always excited to have my car in for service. Hahah
All my issues were never related to the mods so they covered it without question. A friend of mine had same mods and his motor went due to a bad injector and they covered it without question.
Every dealer is different and depends on your relationships too. Some are fair while others will be quick to blame the mods. It's a hit or miss and as everyone says, mod at your own risk.
