I have recently had my octavia vrs remapped using blufin, after approximately one week I started to get what feels like flat spots between 2000-3500rpm in gears 3rd upwards, if its not a flat spot it just has no power then once past this its off, has anyone else had this problem as superchips say its a first, ive seen on some modified octavias that they mention a fuel valve from an rs4, why have they changed it and what does it do, can anyone shed some light on this please.

Have you tried it back in standard tune to see if it still does it? Did you physically go to either superchips or a tuner for the bluefin, or was it a post job, either way if it's the remap causing the problem they should sort it. Good luck and let us know what happens

Took it to superchips head office and they have had a go a curing the issue, they say its turbo lag caused by the wastegate opening to quickly, they have modified the map so it opens later, still has a slight hesitate when flooring it but better, if im not happy they said they would restore to factory and refund, anyone else had issues with waste gate on octavia, if so what else can be done? Has anyone had theirs revo mapped? What do you think of it?
