Probably a bit..

Stock, the ECU needs a 10-12% fuel correction from rich to balance things to stochiometric. This is why bolt-ons have such a big HP effect on this car. By bringing fuel corrections closer to Zero (leaner) the car makes more power yet is perfectly within desired limits for Emissions and correct A/F ratios ..
