Just installed a wideband and its reading 10.2 - 10.6 at idle. What's the ideal safe af ratio at idle and wot. I have a base tune and need to break in the motor before the dyno. Thanks

5.0s like to idle anywhere between 14.0-15.0. Should definitely stay away from any kind of WOT pulls until you get a tune

At and around peak torque is where you want to be a touch on the rich side (low to mid 11's).

14.6-15.0:1 for idle and cruising, WOT should be around 11.4:1
