Below Lora is available for download put into model/lora folder, but you need an additional node installation in comfy-ui.

here the comfy node you need

https://github.com/Lakonik/ComfyUI-piFlow

it works for some other models like qwen, the result is more or less ok (but like all other turbo and x-step loras not that good as original step)

i would use 6 to 8 step ! You can also use "Load pi-Flow Model (GGUF)" loader!
