Did the oil pressure gauge mod, have a question on readings

Hey guys. I did the mod to the truck today, everything seems to be working properly. I have a question about the gauge readings though.

Idling, it is in the normal range, towards the high end. My problem is when I'm on the fuel pedal, the oil pressure starts bouncing and dropping to the low end of the scale. It is directly related to throttle/load.

I realize this is from the injectors using more oil, and I'm getting the reading from the HPOP reservoir. My question is whether or not this is a normal thing, and what i can do to fix it. I'm not opposed to undoing the mod, just want to make sure I don't have a more serious problem.

The truck seems a bit sluggish most of the time, never stalls or cuts out though. Just wondering if maybe my lube oil pump is getting weak or what.

Home made 6637 intake, 3" straight pipe w/downpipe, old school chip, maybe 50 horse if I had to guess. Adrenaline HPOP, stock everything else.

Thanks in advance.

That was my concern. I expected the gauge to move higher at higher RPM like most engines. This is the exact opposite, like the lube pump can't keep up with the HPOP demand.
This is directly from his site "Strangely enough, when engine is hot and cruising the gauge reads where it did with the "liar" setup, but it does read higher cold and lower idling. "

That's not really what's happening to me. What he describes is what I would expect, and pretty much what I'm getting. However, when accelerating, the pressure drops in direct relation to the throttle position. Let off, it comes right back to cruise pressure. The higher it revs under hard acceleration, the lower the gauge reads.
