It could be as easy as a coil just try disconnecting one by one and see if you notice a difference.

Exhaust setup is resonator delete and muffler delete, so it's straight pipes to the end.
I ordered MAF sensor cleaner some time ago but didn't notice any difference after using that.
What would TB be ?
//EDIT
also what I noticed about the MAF sensor, if I disconnect it completely, it doesn't throw any error and the car drives completely the same as with it connected, so might that thing be broken all together ?
