2G Help needed Running lean/only getting 5lbs boost

[VivaLaOC]

So since I've gotten the car in the past month and a half I've done maintenance and added a boost guage and MBC, fixed the oil pressure sensor and a few other things I can't think of off the top of my head. Anyhow, so when I'm driving and I'm in any gear I only get maximum 7lbs of boost normally only about 4 or 5. I checked the IC for oil in it and it had some in it, not a super significant amount but there was some on my finger when I pulled it out. I was getting the coolant temp code p0125 for a little while but that has stopped, and I also had a TPS code but that hasn't came back, but the other night I had a code for fuel trim bank 1 pop up and that was the first time for that one. I know it's because of an O2 sensor but would any of these things cause me to only get max 7lbs of boost? It's definitely running lean it idles normally at about 875-925 rpm but any help would be greatly appreciated so I can get the full potential from the car. Also, no I don't plan on running anything like 18lbs i just want a little bit over stock

Did you fix that big hole in the IC pipe?

Yes, I managed to patch it up and everything is working perfectly now

You don’t patch holes like that. You replace the hose

No offense, but that's a placebo effect or just a band-aid.
Please do a boost leak test properly. You will never fix all leaks without boost leak test.
You will be surprised at the number of boost leak you don't actually notice by looking. After fixing all leaks, you will be surprised by the difference of car’s driving performance with and without boost leaks unless the car has further issues.

I don't know exactly what did it but I fixed it thanks for the help everyone!

You found and fixed some issues. You should still test the entire system and proceed with maintenance. If that giant hole was present what else is lurking and what maintenance hasn't been done??
Do not assume all is good until you prove that it is.
