Check Fuel Pump 2 fuse which is located on the auxiliary fuse panel. On the passenger footwell, remove the cover and look under and you will see a small panel with some fuses. One is marked FP2, check it.

If Fuel Pump 2 does not run, you don't have enough fuel on Full Power mode when the engine is WOT and this causes the lean problem.
