Pressure regulator mod?

Anybody know any info on this modification. Manufacturer, specs. ect.

It's just a modified stock 233 regulator. There are a few companies that make one like it. I made one myself that looks just like it

Yea I knew it was a stocker, but I haven't been able to find out anything on the adjustable modified top.

There isn't much to know. All they did was add an adjustment screw to the preload spring inside the regulator. It still works the same way as a stock regulator...fuel pressure increases 1 psi for every 1 psi of boost. It just adds adjustability to the base pressure most likely in the 35-60psi range. It's hard to say who made yours since most of them look the same.
