In a word no.

I suggest calling V8 developments as your engine/injection system is not standard and getting this mixture wrong could cause pre-detonation and bye bye engine.

Ideally you need the lowest emmision readings possible for CO and HC but that usually means running a lean mixture which potentially causes issues with pinking/predetonation. Especially ones with tweeked engines.

Personally I would not touch the mixture/ignition/ECU because they all affect the sweetspot. The quickest and easiest way of getting the car adjusted is with a Mark Adams session, or get V8 Developments to set it up. They supply the engine and should know how to set it up. He/they can look at other factors and make adjustments that give you an optimum across the range. Adjusting the mixture via the mixture adjuster on the airflow changes it across the rev range and the engine may well be leaning out as a result in parts of the band.

My guess would be a 0.9 but I have this bad feeling that this is too lean for the engine and not a good idea. With my engines I get them set up by the builder/Mark Adams and then don't touch them.
