Has anyone fitted one of these? I used to have a 'Dragon Digital Tunning Box' on my Mk1 Fabia vRS and it was very good. These appear to be very similar. Have just bought a 140 Superb and thinking about a remap, but not going to pay £500 if I can get similar results for £79

I have a chip express box on my audi a4 tdie 134. Ups that to around 160bhp. Turns a sedate cruiser into something with a bit of oomph. No problems in 2 years.

It will be a straight transfer to the 170cr I have on order. Which will take it to circa 200 bhp and about 7.7 to 60.
