Hello all. looking for some advice/help while i wait for my tuner to get back to me. I had issue with loosing fuel pressure at wot droping below 1500 psi. Tested the relief valve and that was my culprit. Sent logs over and came back good. Few months went by and everything was good intill it wasnt cause of where im at now.Iwas driving one day amd it just seamed off to me so i pulled logs and sent them to my tuner and comes back with my car is extremely lean fuel trims and w.o.t afr are off by 15 ish %. I boost leak/vac check the car and found that one of my p.i injectors are leaking. Replaced the o ring on the injector boost leak checked and found now i was leaking from my mac 3 port out the wire holes. i ordered a new one installed and took these the logs that are attached. I let off cause i seen afr go into the 13. After the data log i noticed that the a.p only stated at max to hit 26 psi of boost when tuned for 30 psi (told by tuner i could/would see 31/32 psi on colder days witch i have seen exactly that 30-32psi) With me letting off i chalked it up to me not giving enough time to build. I did 3rd gear and never made more then 27 psi so lead me to belave i have another leak some where .......so today i did another boost leak check and again coming from the p.i injector o ring that goes into mani replaced that one again and watching the ap and still seems off (will pull more logs later after rush hour traffic) thanks for your help just kinda wanna make sure im on the right track and dont have another issue somewhere and end up wasting time (tuner/mine/yalls)

Take a new idle log; the one you've posted (3) appears to have perfect trims, which really isn't possible (there's always some variance). This makes me think either you took the log from a cold start before the O2 kicked on, or there's something going on with a sensor somewhere.

okay i will the idle log was after the 4th gear pull but i pull another tonight after im off and load it
 
This idle log is much better. As was expected, your trims are all over the place (which is normal with a 4" intake. You could benefit from adding a honeycomb straightener to this intake, and possibly replacing the filter. How old is the filter btw?
