Tune = Warranty, Gone.
Flashback, March 2009 I brought my M3 to the dealer for a sound coming out of the engine bay.
A few days went by and the dealer told me I exceeded the computer max governed velocity more than a few times, and went over the set redline by 100rpms 1500 times.
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?
