I did mine. DME tune, down pipe and custom dual valve exhaust. Exhaust is following DME logic.
Result dynoed is 556hp /780nm
Just keep in mind depending on your local bimmer dealer you will likely lose warranty. But it's made my car into a beast and I have had zero issues. My tune is completely within engine tolerance. It's a stage 1, stage 2 requires a different air filter plus gasoline pump. That will add around 55-60hp more.
