Have you checked the hose that is supposed too run from the map sensor too the rear t
Yes, I had heard of that issue, I replaced that hose & it's clamped down, I'm only getting 10psi as it is now, one guy told me to clamp down the return line hose to see if the pressure would change, it went from 10psi to 50psi when I did that, he said for some reason the fuel was getting by my regulator, he's sending me another one but I suspect that's not gonna change anything, I've rebuilt both tbi's so as of right now, I'm just frustrated beyond belief cause there's nothing else to replace or check, ugh

WOW! This thread has spanned seven years, that's crazy for just a "what to do with CFI". I'd keep the CF IMO, but if you MUST swap it, go with EFI setup or do LS swap. My 82 runs rather well.
