FreeU is a method allowing to re-weight contributions from the U-Net skip connections and backbone feature maps, potentially improving generated image quality. Details are described on FreeU project page. It allows you to create both punchy, as well as toned down images, depending on parameter values - see examples below.

Prompt: "modern sports car", seed 0. Other settings left at default values. Generated using Fooocus-MRE v2.0.78.2.
