ecotecs are supposed to be in the 10’s from gm, so 12’s are high. that might not be true for other engines though.

Should that be true then your statement would be correct, but…

@dyingwish

Are you sure, that seems super rich…like ring-killing, cat destroying, carbon clogging rich. When he tuned your car, did he continue to lean out until power gain disappeared? Stoic fuel burn is NOT dependant on motor, and I am puzzled as to why an Ecotec in particular is like that

That is a more accurate statement.

Who told you that Ecotech motors run 10:1 AF?
