The old reading at operating temp was probably 60 psi, and now with MMO I would say its at 75 psi and steady at 2100 RPM. There are no numbers on my gauge, just a low and high normal scale.
Something else it did is when driving in traffic the oil pressure gauge moves faster and it has a more consistent steady increase as I go through the gears. Before MMO, it kind of crept up slowly and as I shifted it would drop down quickly then come back up slowly. Now it's a more fluid measurement that still drops down a bit as I shift but it comes right back and keeps increasing on the sweep of the gauge.
This all tells me MMO is helping my engine. MMO works great. Anyone who reads this and is thinking about trying it, go for it.
Normally MMO would not affect oil pressure, but it is possible that you had some buildup in the oil pump itself that the MMO cleaned it up to allow it to pump to it's fullest capability.
MMO will also help clean out oil passages from sludge and varnish (I think varnish IS a problem for restricting oil flow and locking in heat to cause the engine to run hotter) to allow better oil flow through the whole system.
