The article stated that using Dreamscience software Pumaspeed were able to create a custom engine map enabling the car to run on 95ron fuel - however this was effectively achieved by turning down the boost & running less power so the car could run the lower ron fuel without damaging the engine
As standard, from the factory, the Mk1 FRS requires, and is designed to run on, 97+ ron fuel
