The price of the race chip varies per model and vehicle.
They have 3 models but not all of them are available for all of the vehicles.
The G63 I have the GTS Black version which was 799 (USD) + 50 for the blue tooth app.
The BMW X1 Race Chip sets you back 599
If you plan on keeping the vehicle for a long period of time 2-5+ years its an awesome investment. :)
Cheers!
