Default weird 02 readings and long trims

With a lid my car runs quite lean at both part throttle and wot. The long trims are a + 6 at part throttle and +9 at wot with 02 reading 880. If I plug in the maft I have to go +15% base to get negative LT's at part throttle and 0 at wot. Then my 02's read 920. I would think that if I'm running lean at part throttle then I would be running rich at wot. The car feels stronger though running lean with no maft.
