ok so i just installed my wideband and i have it reading off the passanger side downstream? just curious to know what everyone else's a/f ratio is? at idle mine is at 15.6-16.4...and in gear with load at like 3k rpm its goes down to 12.4-13.1 around there? i wish i can do a log to show you guys but im in the process of breakin in clutch so thats why i only saw up to 3k.

any feedback would be great.

best torque seems to be around 13.1 for me, of course the AFR always fluctuates. it's not the most precise measurement

 

In maxima world, where I live , most people say the vq30 responds best to an AFR around 13-13.2. Seems to be good for NA power without worrying about knocking. I wouldn't be surprised if it's very similar for you as well...
