I bought one of these and would like to know if the pressure can be adjusted.

I have one off a 92-96 kit. How can find out what ratio it uses?

why does it suck? I'm using a vortech 12:1 and I love it. I had to raise my fuel pressure quite a bit otherwise I'd lean out at around 3K when boost was just getting going, but other than that, it's perfect.
