The o ring inside my noise maker seems to have a very large gap in it. So its obviously not sealing properly. What issues could this cause

Mine is solid all the way around. That ring seals the noisemaker to the Intake tubing... if it's jacked up like that it could potentially cause a boost leak.

It will cause a boost leak.
But because our cars fuel off map pressure. it wont run lean. You'll just work the turbos a little harder or have a slight lack of power.

Well I plugged it but I'm still having the same issue. Car just lags off the line until 3 to 4k rpm then acts normal. I don't know wtf it is.

Split and loose turbo piping is a common reason for boost loss, so you will have to check the hoses atop the intake manifold, the hoses coming to/going from the intercooler, etc. Splits are usually at the clamps, and usually on the undersides, so you have to feel for them/see if there is an oily accumulation underneath.
No codes at all? Are you monitoring boost levels?

I dont know how to monitor all that. What do i need? No check engine light are on either

oh and heres another thing. if I take it on the highway for a trip and go back to city driving its fine for a couple days. then it will start being sluggish again. I just wonder if previous owner tuned it and then the dealer detuned it and didn't put stock parts back on
(Android) Torque Pro software + an OBD adapter is a quickneasy way to monitor vitals on your SHO. It will also allow to check/pull codes from the PCM. Most codes do not set a check engine light, only the ones with potentially serious consequences.
How many miles on your SHO, and when were plugs last changed? Plug condition provides clues re: engine operation, if that is the culprit.

I've had the car a few months and changed the plugs maybe 3 months ago. What would be a good Bluetooth obd adapter

If not using for heavy duty purposes, a Veepeak adapter will work well.
For best speeds and reliability, I highly recommend the OBDLink MX Bluetooth adapter. I am going on 4 years with mine now, 30 ms data intervals. Forscan Lite. Torque Pro does 100ms intervals max, so easily in range.
If you should decide to log data, the longer the time you continuously log for, the more RAM your device should have. I prefer at least 2GB as I will occasionally log my roadtrips. Not very long, but 4+ hours routinely.
The MX also runs cooler than the cheaper adapters, which probably contributes to its superior longevity. Electronics and heat, no bueno.
Try not to have your other devices too close by. Yes, wifi will interfere with bluetooth signal strength, due to emf if nothing else.

I have the OBDLink MX Wifi version(Bluetooth one doesn't work with iphone) and am very happy with it.

Shodded...sorry forgot to mention the car has 101k on it
Aside from the usual culprits - boost leaks, turbos, dirty intercooler - the throttle body motor sometimes fails, have not heard of the TPS failing on this Gen SHO, but another possibility. TPS part number - 6L2Z9B989B/D. Looks like the pics in this listing (the sensor next to the noisemaker, I believe, that you show in the pic):

there is a lil bit of oil in my intercooler. would sucking all that out maybe help my issue?
check it out with the oil dipstick, see how deep the crud is. it is possible some of it is getting sucked into the engine, but should be worse at higher rpm's. so not really optimistic, but still worth a check.
Chafing knock sensor wires probably don't fit this scenario either.

I had checked it the other day. my driveway has a slight downward angle so I backed the car in and check it without jacking up driver side to let the oil go to passenger side and there was about half a finger nail depth of oil

could it still cause the sluggishness or should I invest in the odb adapter and check the car out
Cant definitely rule it out, but I do not think so. Investment in an obd adapter IMHO is a must with these cars. And you have a "situation" at hand, so you need to see what the car is telling you, then go from there.

just wish they were a bit cheaper right now lol
