Basically, I'd like to look at some other peoples data, specifically at WOT from 5300-redline.

With my setup I'm hitting 19.5-21psi boost in that range and it's making a hump in my AFR where it goes from low 11's to 13.2 in that rpm range. Unfortunately, I don't have the add-on fuel pressure sensor, so I'm having a hard time telling what's happening. Basically, as soon as I pass 19.3 psi, it starts to go lean.

I'm fully aware that NW has the adjustable fueling kit, but I really don't like the complexity of it. I would think with the Walbro 255lph pump and 550cc injectors, I would be able to get this tuned properly. My next thought is that I might need the 55 fuel pump, but really don't want to throw any more money at this.

Any help/suggestions would be great!
