I've had a few different remaps on my car since I bought it, the latest and final company is Shark performance. They offer good customer service (I spent 6 hrs there at the weekend getting my remap tweaked, free of charge)
Also, if you are lucky, they quite often do group buys on Briskoda, where you can save £££££'s.
I took the option to get an sts unit with my remap, which was free with the group buy. The unit allows you to swich between maps, stock mode, imoobiliser mode etc, and also can be used as a fault code reader. all from the comfort of your residence, also this means you can just get the map emailed to you if you live too far away from their headquarters.
All the 3 dyno results below are off my car. I though the bluefin was by far the worst of the stage 3 remaps. My car had issues with Revo, CEL light kept coming on, and Revo werent very helpful, and had to get to get a refund.
The benefit of the shark map is the fact that it has very smooth delivery, and also if youre worried about stressing the engine with Revo stage 2+, this is a good compromise. I also achieve good mpg aswell.
