Are you sure? I thought that was WOT pressure. (At idle with vacuum line removed from FPR.)

I already corrected this in another thread. It is not 43.5 at idle. It should be ~43.5 with zero vacuum reference. That means with the vacuum line removed at idle, at WOT, or Key On Engine Off when it primes.
