"Hi everyone, I'd like to get a Stage 1 remap on my Skoda Octavia Mk3 vRS. Can anyone recommend a good tuning garage in South London? Thanks!"

Horses for Courses really, everyone has their own idea as to what they would like to achieve.

My advice would be to look into RacingLine and Revo authorised tuners in your area and take it from there.

Or APR official dealers. People with a rolling road / dyno preferably where ever you go. Best after the car serviced and new plugs and filters fitted and running well on E5 99 ron minimum.
