I've had the Race Chip GTS Black fitted for about a week now ... and have been seriously impressed with it.
The power delivery is noticeably smoother than stock, as if it eliminates the slight turbo lag.
Really happy with it, and the App control is very easy.
I replaced my brake pads with RG Sport's 'low-dust' pads too, and new tyres all-round ... so hopefully the improved acceleration & top-end speed can be managed better
