I suppose most people aim for 14.7 (dependent on fuel) for most rpm driving and 12.5-13 afr for wot?
My question is why 14.7 or even leaner for cruise, other than emissions or gas mileage?
Would you gain more power through the rpm band by running a richer mixture say in the 13s or along those lines? Obviously sacrificing gas mileage but depending on application who cares for mpg? Lol
When i read Master EFI tuner he aims for 12.5 through the entirety rpm range for best safe power (medium large cammed ls1).
Just overthinking stuff here looking for opinions.
