Notchtop sr low compression??? Help!!!

Ok guys in need of help/opinions
I've got a Zenki notchtop sr swap in my kouki just recently upgraded to a top mount turbo set up bigger injectors bla bla 15lbs running of the waist gate using apexi power fc we'll decide to do a compression test before upping the boost and tuning it on the dyno and what I found was disturbing and confusing.
Compression numbers across the bord were all 117psi -121psi when I saw this my heart sank
This was tested with the engine thempature right around 175 degrees Fahrenheit all spark plugs out and at wide open throttle.
So decided to simply pour a spoon full of oil in each cylinder prior to the compression test. I tested the cylinder dry and then wet right after and all numbers remain the same one maybe two of the four cylinders jumped up 1psi. So next I pulled the valve cover to see if maybe it jumped a tooth or something,
Well this was also confusing to me there is supposed to be three colored links on the timing chain one to be matched down at the crank and two to match up at the cam gears well all I had one one silver link I marked the one I saw to make damn sure I was not mistaken when seeing it again lol and also wiped off every individual chain link on this damn thing and nothing,
Timing light reads 15 degrees as well as the power fc I'm very lost here car runs and pulls spectacular no smoking, knocking,missing,no blow by. I need help.
I'm going to be looking into doing a leak down test also gotta do some research as to how to do that I've never personally done it. Also Vtc gear is nice and quiet verses being hella loud when there bad any help is much appreciated guys thanks for your time!
