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.

When I had that mod on my 94, it did not do that. It would run lower at idle and increase with RPM (I just didn't like the gauge sweep range and restored the stock setup). You may need to hook up an aftermarket gauge (electrical or mechanical) to see if it does the same. If so, you could have a possible LPOP/pickup tube issue (in my mind). Cheers!
