Been running stage 2 on my F30 335i N55 for about 50,000 km now. Wanted to share my experience for anyone worried about reliability.

Mods: catless DP, FMIC, BM3 stage 2 map on 98 octane.

Zero issues so far. Oil consumption is the same as stock. No warning lights. I do oil changes every 8000km with Liqui Moly 5W-30.

The key is a good tune from a reputable tuner. Dont cheap out on the map.

    Great to hear about long term reliability! Im at 20k km on my N55 stage 2 and no issues either. Good tune + regular maintenance = no problems.

    50k km on stage 2 is solid data. Thanks for sharing. This gives me confidence to tune my own 335i.
