Selling my Race Chip GTS Black I bought for my BMW X3 M40 (G01). I bought this and a JB4 at the same time to compare. This came first, put it on, loved it. 1 week later JB4 came in, installed and never took the JB4 back off.
Great deal for someone looking to increase their HP. Used for 1 week. This GTS Black does not include the app, you can upgrade it via Race Chip I am told. Paid $700 for it. Comes with manual and box.
Selling for $500 +shipping obo.
