Depending how far South you are, Regal in Southampton are my local guys for VW stuff. They can map with APR and fit pretty much any hardware you want. Dont think they do Revo though, might need to pop up to London for SCC or AMD as you mentioned.
Thanks, I'm half hour from Soton so they sound ideal, do you get all your servicing done there too?
I will do once my warranty runs out (if I keep the car that long though)
Decent guys and have loads of time to chat through stuff if you want. They will dyno before and after the map to show you the results.
