That's the thing, I've only used high octane fuel (RON= 102) ever since I got my car, and kept using it after I installed the piggyback!
This is one of the reason why I went with the DTS box as it is mapped in a way to allow for variations in RON.
You will only ever get quoted increased figures if you use a high RON fuel but the people at DTS said that you will get an increase in performance even with 95 RON on there system.
