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
its a custom map r-tech do for most ppl not a generic map 
an revo are pish end of
I rang R tech when I was after my map, they told me they have 1 map, and that's a 98 ron map which they recommend 
I asked if they could do be a custom 95 ron map, which they couldn't.
So who do I believe? You or R tech.....MMM let me think
Oh, and how the f**k can it be custom if most people have it?? 
r-tech prob told you running your car on 95 would not see the best results an you didnt want to pay to extra for decent fuel 
and ask this guy if he has a generic map supposedly the only 1 r-tech have as you say

Just tried to find the email, but its deleted as it was around April.
I was fed up with putting Optimax or Tesco 99 in my RSK B4, hence why I bought a couple of Golfs to run about in.
You can map them to run on higher octane fuel, but I cant get it without travelling a 40mile round trip.
These go well enough for what I need on normal stuff, in fact there is only about 10bhp between the different octanes, and as said before, no 2cars are exactly the same anyway. Still more than the earlier Golfs with the K03 turbo maps to.
