fuel pressure wont go no lower than 43 ?

Not much to go on there, but I just woke up and think I'm missing something. I'm not sure how the stock pump is in there with Nitrous and 24's.
I'd have thought an upgrade would have been requisite for those mods.
Do you have a lean code or ever hear pinging?
If the pump is original, it would likely almost be a preventative maintenance item to replace the pump with something a little larger.
Good luck.

Apologies - After reading your post, I somehow thought your issue was that the pressure would not get up high enough (you desired 43 PSIG and it would not get that high). Once I saw the thread title again (and after some caffeine), I realized my mistake. Disregard the lean code stuff, etc I asked about.
It sounds like a stuck FPR or pinched return line, but I don't run a Kirban so I'll let the other guys answer for you. Emailing the Kirban folks might not be a bad idea.
If you have a fuel line crimping tool, you could carefully crimp the return line and see if pressure goes up even more. If it doesn't, there could be a restriction in the return line. On my '88, I had one right where the return line goes around the fuel tank edge (it was kinda pinched). I'd take a quick peek (it's a good time to make a sheath for the lines back there - if like mine, they are real close to the tank and exhaust).
Again, sorry for my misread initially.
