inexpensive TBI fuel pressure regulator

[CyberSniper]

Is there a such thing as a TBI-range fuel pressure regulator (12-20psi) that doesn't cost a small fortune?

You already have one in the top of the TBI. There are instructions I think on third gen on how to modify it to be adjustable. The link is in the Links post in 73-91 forum.
