AFAIK, the difference is due to 2 reasons:
1. Marketing (a reputable tuner which has a co-operation with BMW ''cannot'' offer the same tunning for 2 different models).
2. All the tuners, at least up to now, offer a tuning box (paralel ECU), which is based on the stock ECU (it alters the sensor signals). Thus, it is limited by the stock ECU in terms of performance.
