best air/fuel ratio

What is the air/fuel ratio you should look for at the different throttle settings, Idle, cruise, full throttle.

From my study. Optimum - 12.8 peak torque
Optimum -13.2 peak hp

That depends on if the the motor is supercharged or normally aspirated.

Tell us what setup you have and then we can advise accordingly.

You can throw my numbers out the window. My opinion was for a n/a set up.

I have a post here with the info you are looking for. Look for "Wideband O2 upgrade".

You want to be around 13-1 at idle and as you go up it needs to richen up so that you end up around 11.8-1 at your max rpm.
