Another happy Revo customer here

This site is bias to R tech, even though they only do one generic map.
The Revo map has also been well developed, but can be tweaked once on your car. ie, I had mine adjusted for 95 ron unleaded, not super as that's what I wanted.
R tech remap is tuned for 98ron.
My other AUM Golf GTI has a remap Science £200 remap, which is actually quite good too. No probs so far
