Let's look at the risk of a spang. 1,000's of tunes on the market with previous models in use, several hundred now with this one. The N20 being built to be a platform for much higher HP with only bolt ons and tunes from BMW - ie. is a very solid platform in stock form. The Stage one being 'mild' for this platform. Key issue being fuel/air ratio is well n truly covered in this tune. The BMW tune if & when it is released will likely be very similar, but will be packaged differently to try to differentiate & to try to justify cost,... etc....
The risk is extremely low. The person I know who has fitted one is extremely happy with a very solid mechanical racing background and a stickler for doing things to a very high standard and does his homework very thoroughly. His opinion is that this is simply a wake up package & that the f30/328 platform is designed to take much higher stresses than even the stage 2 beta numbers and still operate like a stock vehicle in terms of the chance of mechanical issues. (other than perhaps the vehicle prompting earlier service intervals which can happen under many 'stock' conditions as well), but in the end as always, each to their own. Enjoy your driving!
