ok so i drove my car for a day and it drives fine. the next day i drive it and it starts to bogg like its not getting enough air. Checked all my ic piping and couplers and they are all still on tight. its starts to bogg around 2800-3000rpm. any ideas of what would cause this.

My car:
3sgte swap all stock with 2.5" ic piping and 3" full custom exhaust piping

check ignition cables. they might pop off and they might be just worn out and transfer the energy to valve cover. especially when hot.

I think i figured it out...not sure if this has anything to do with it but there was one bolt missing for the turbo oil line, I think its the oil feed line(the one right under the turbo). After i bolted that one back up, it started to run normal again. But i'll check the thing you told me to do and go over it just in case.
