If you don't like the reviews Rick at Unicorn Motor developments is just down the road in Stockport. Not Revo but is there any reason you have decided to get a Revo remap ?.
I'm already Revo stage 2 and my local Revo dealer is no longer a dealer.
So I'm now looking for somewhere else as I now have a Sachs 4 paddle clutch. I now need the high torque file and there's a version 4 software update which is better.
