Pushing in the bottom plug increases full throttle/full boost enrichment control pressure, and thus, leans the mixture. For example, if you have AFR readings of mid-high 9s (too rich - causes misfiring during full throttle acceleration), and push the plug in about 2mm, you will then see AFRs in the mid-high 11s (typically).
