A power enrichment ratio of 1.17 equals an AFR of 12.05:1 which is obviously not lean. If your wideband is reading 1.17 lambda at WOT, then yes, you are seriously lean. But we have no idea what your mods are. I would normally suggest you post your tune and datalogs for review, otherwise we’re just guessing.
