It took around 2 hours. I was in the waiting room so not exactly sure what they did. Could hear it on the dyno though.
They get good reviews and tune some fast machines.

There's also Celtic Tuning in Newbridge on the outskirts of Edinburgh. I think they do off the shelf maps. They have no dyno and suggested SOS for the dyno too.
Got the Skoda done a few years ago at Falkland Performance. Cost a fortune to get it running right. Cant remember the price.
