Ok thats pushing it on the lean side on an off the shelf map. Get yourself tuned.
14.7 at idle is exactly where it's supposed to be.
Running lean/unreadable AFR's when you're coasting/letting off the gas is COMPLETELY 100% NORMAL, don't worry.
But ya, you're running a bit too lean to be in the comfort zone when at WOT.
