Default C/O% at idle?

Took the Saph for its mot today, and the c/o% was 0.50, to me this seems abit low?
So I turned it up abit to just under 1.0%
Any ideas what it should be?
It's a stage 3 greens, t34
Cheers shaun

Don't know really, I would seriously be taking it for a setup if it were me though, to see the reason why!

Thing is with the "Global mod", aka CO screw, you alter the whole fuel map as a percentage, so it's not as easy as just tweaking it, as the fueling can change throughout the map!

turn the co pot 5 turns clockwise then turn it exactly 2 turns back
this will set it at what is known as zero pot position
recheck the co
allowable adjustment is half a turn in either direction
2-3% idle co when hot fans off, no load non lamda
