I just bought the pressure regulator today. I will be installing it tonight. I installed a gauge last night and the OEM pump is pumping around 8-11psi. (the needle bounces)

After changing the vacuum and timing I don't get any hesitation during acceleration and much more pep. It is seriously like a completely different engine. I am surprised those minor adjustments can make such a difference.
