Just out of curiousity (I have a ONE and not an MCS)... if the car is now running with both increased performance and better fuel economy, does that mean it's now running leaner than stock? If so, I've heard running an engine on the lean side can be a little risky at higher boosts and rpms - how do you get around this?

All the best,
Andrew.

Hi Andrew

Adjusting the timing, allows optimised fuelling. Fuelling is in relation to engine load, and because we are optimising the ignition and fuel maps, less engine load - less fuel request.

Running lean is more than risky, its fatal for an engine. I would not let a car out of the workshop if it was running lean.
