    So with all the different places/excel sheets to calculate I should be 96-100lb per injector. I think I need to go a touch higher because I am maxing out the VE table in a few places but the problem for me is the red spring I have for the fpr maxes out at 22 and I would like to be able to got to 23 or 24 but can't find a spring, may just go external fpr unless anyone knows where to get a spring that has a range of lets say 20-26ish psi.

    I got this spring from ebay, and running @ 28PSI with the adjuster barely turned in. I think it's from a 95-96 7.4L, so this may not help unless you go higher than you mentioned.
