Any one tried running lower pop pressure?

What would be the advantages to that?

Allows a wee-bit more fuel in a given injection event window. (The injection event window becomes wider). It perhaps comes at the expense of a little slobbering at the start and finish of the event.

I run mine at 235BAR (+/-2.5)

I think mine are set to 220 or 227 bar. Burn kinda dirty. I need to pull them out and have the NOP bumped up some. It runs pretty damn good how it's set now, but the smoke is kinda crazy

I was thinking it would add more fuel and increase duration w/o having to bump timing. BC did you have any change in smoke or haze or any before and after dyno #s?
