Thanks man.
I expected for mapping the engine for 95Ron there would be a reduction to factory power for it to run safely but wasnt the case. He was able to get the car to run on irish petrol without any issues or knock and still maintain factory power.
He had it on the dyno for most of the day until he was happy with it, then a quick road test to make sure it was running right. Very pleased with the results with Aonghus.
