I had my 156 2.0ts (selespeed) remapped by RedDot this week, it took my HP from 146 to 159, but better than that the response from the car is much better, take off is quicker, it feels much livlier to drive. Well worth the £200. (and i got a cup of coffee when i turned up which was truly appreciated)

Later today, for those that are interested, I will scan and post on here the before and after printouts.

It is IMHO worth doing although the gains arent as great as for tubo cars the drive really improves, and , from my experience, I would recommend Red Dot.
