They have no English Agents but come highly recomended

Just thought others might be interested in there tuning boxes if they are as good as Ive been told, looks like they dont do anything for the new Superb though, must be that DPF again !!

I'd not bother; doesn't look like they do anything that a Tunit or a remap won't.

never heard of them

That box on their webpage is identical to a Tunit one I had on my Focus a couple of years ago. The same clear front with LED and jumpers sitting behind it...
