Low Oil Pressure aft studs/egr/oil cooler

I just got my truck back yesterday after getting the headgaskets replaced and arp's. Two weeks ago I did the BPD egr cooler and new oem oil cooler. Truck is an 07 250. 75xxx miles.

So after driving it about 50 miles after getting it back my low oil pressure light comes on. This only happens when I'm off the throttle/braking. Checked oil right away and there wasn't ANY on the dipstick. Dealer forgot to refill it! Ok, so I ended up putting 2 gal of oil in it to get it back to the full line. Still does it. After a quick search here I found one guy who had this exact problem and it turned out to be his sending unit. any other opinions on this?

Also, I've been monitoring my ICP voltage and psi. at idle my ICP V is around .9 and goes up from there. My psi sits at around 560 at idle and goes up from there. Sound normal? Any help or insight is appreciated!

ICP sounds normal. .8v running is typical

I have heard of oil pressure switches getting contaminated from parts cleaner. I always remove the EOT and EOP before cleaning the oil cooler cover. haven't had one fail yet after a cooler replacement.
