I have REVO stage 1 on my ED30. I paid £500 so about the same and it has been well worth it. I also had some Tarox performance discs and pads fitted at the same time.
Yes of course I was expecting the power gain but was not expecting the way the car completely changed. The charachter of the engine is different, it sounds better and idles smoother. It is quite happy dawdling in town traffic and cruising. Its far too quick to say that is should have been this way from the factory but the driving experience is so much better you have to think that VW leave a lot of headroom in their engines.
REVO is supposed to be an aggressive map, not sure what that means, I suppose the gains are better than APR or Superchips but then the downside is the wear on components.
Its much quicker off the line but the real perfomanc gain is mid range, its still surprises me how it reacts like a bullet from a gun and just disappears down the road with me clinging to the steering wheel.
So no negatives from me, fuel consumption is even better !
If there are any downsides then it could be that Stage 1 is just the start of a slippery slope of mods. Exhaust, Air Intakes etc. I have decided to stop where I am. In my view Stage 1 has completed the car.
The day I had the Map done I was heading home and was being followed by a black Golf MK6 GTD with DRL's and foglights on. It was 2pm in the afternnon and sunny so you know the type !. He ( looked like an estage agent ) proceeded to glue himself to my bumper for several miles. Joining the M1 on the slip road he was still attached to my car so when I checked that the motorway was clear I could not resist trying my new toy for the first time. Within seconds I was at three figures and still going, looked in my mirror and I could still see his DRL's and fog lights way, way in the distance. Very childish and very satisfying ! I was laughing out loud for miles. Was even tempted to let him catch up so that I could do it again.
