That's too rich, but it's definitely safe to drive. If air/fuel gets 12.0 - 12.9 then start being concerned for the 'safety'. You need to have it tuned, however. What mods have you done to cause it to be so rich? Is it also rich while your in 'boost', if so, what is the A/F through out the RPM range (boost range)? You would normally be looking for an 11.5 or so, give or take .2 either way.

My mods are 3 inch turbo back, cone filter mas adapter, mbc set at 20 psi, all tuned b buschur racing. It dips down to 10.2-10.0 when i let off the throttle after being at full boost. regular driving its fine.

No! The higher the # the leaner....the lower the # the richer....you my friend are too rich. If anything don't mess with the boost and get a retune.

Maybe your sensor is going bad, you should feel a reduction in performance running that rich. Also check your plugs for black deposits. Normal burning plugs tend to be more brown than black.

all right i went and filled it up. Came back 15.8-16.2 idle 10.7-11.2 full boost 21psi peak holding 19-20 psi (boost contoller is awsome ) dips down to 10.2-10.4 for a split second when you go wot from 3200 rpms.

I run 93 octane. Wide band is the new AEM UGEO installed a month ago.
