Just been for another spin and it is superb. Loads of smooth creamy power that just keeps building and building, it flat hauls with no nasty spikes, no holding back. Seriously impressive.
Worth checking out, superb service, really knowledgable and seem like top blokes. I'm now dreaming of those RS4 turbos and custom remap they keep mentioning, and that SRS software dongle etc , etc, etc.
PS. I am pretty happy.
