I'm over 500 HP now by a fair chunk (12mm stroker CP3 and 100% over injectors) and I've never had any problem holding rail pressure. After watching the Fleece video, I feel it has no real benefit for my power level. So why risk the burrs getting into your injectors, leaks, etc? That's why I didn't do it.

Thats what I was figuring as well, but like I read on other threads, some people werent making max actual rail pressure until they did something as simple as this
