Air/Fuel Ratio Question...

I am about to install the diablosport predator ''performance'' tune on my Ls1 C5.I also have a AEM w/b and I need to know what is the correct AFR at WOT/IDLE,etc.Rather play it safe even tho I'm pretty sure everything will be ok.

Car is currently stock.BreathlessPerformance Vortex and 4.10's are next mods.
Cam and LS6 intake later in the summer.

Thank you.

14.5-14.7 partial throttle
12.8-13.3 at WOT

Can someone confirm this?

At WOT it's your choice really on that matter. You can run lean as 12.9 up to 13.0 or go safer from 12.7 to 12.8.

but you're correct on part throttle, 14.7.
