Their website is nice, but doesn’t really give that much technical info. Any help?


Thanks

I just got them in stock recently and just had the RaceChip GTS Black installed on my G30 540i replacing the RaceChip Ultimate that I had it since May 2017.

I have yet to understand all the details too, which I will have meeting with them next month.
But, from my understanding, those 7 maps are will automatically used based on the data it collect from your car and use which one is best for your engine.
The only setting it will give you on the module is Off, Eco, Sport, and Race.

As far as a MAX gain, in my 20+ years experience in the industry, don't trust it until you dyno it.
I do believe in the gain, but the number, I suggest not to take it too seriously.
There is too much variable to proof that number. Climate, Sea Level, Gas quality, etc.

But based on my customers VBOX data, there are a very good improvement just by using RaceChip.
I got guys with F15 X5 50i (N63tu) and F85 X5M (S63tu) did a VBOX data, and the number is very impressive.

I have yet to get one VBOX, but I don't think I will since there are no open road when you live in a big city. And the closest dyno place is 1 hour away and it is not cheap.
