Here's my Racechip Dyno I did past weekend, Racechip has been installed since beginning of December 2014.
Reasons I went with Racechip? I have no experience working with cars under the hood or modding or tuning, wanted something that would increase performance and improve MPG at the same time. RaceChip® – plug-in up to 31% more POWER and 15% ECONOMY. 18 years of experience. Made in Germany. Rated Best 2013 ChipTuning Box & won the review of EuroTuner Magazine

How RaceChip chip tuning works
It read data from the engine control unit in real time, and optimise many characteristics. These data include items such as injection timing, injection quantity, injection pressure, boost pressure and air mass. In addition to an increased engine power of up to 31 % you can also save fuel at the same time. But that does only work if you – encouraged by the driving pleasure – do not step on the gas or accelerate more than you did before without your RaceChip®.
Fully stock X3 w/ half tank of Valero 93 octane, xDrive
Stock setting for Racechip N20 is C
1st run is baseline
2nd run on C
3rd run on F
4th run on 1
5th run on 4
The Racechip settings are from Lowest 8 to highest 7
8, 9, A, B, C, D, E, F, 0, 1, 2, 3, 4, 5, 6, 7
I feel Racechip on F could of given a better number but it's whatever to me, at least Dyno also proves its some more than a stage1.
