your learning view looks pretty reasonable. that would indicate that your fuel delivery and air metering are ok. a massive boost/vacuum leak that would cause that kind of issue would show up in the trims. you could test this with an intake pressure rig.

a coilpack/plug issue USUALLY shows up as misfire codes in the ecu. however, there is no way of knowing if those have been turned off in your car. and again, gapping IR plugs is generally avoided because of how delicate the center pin is.

like Kastley85891, what DOES concern me are your stored codes for TGV operation. TGV codes CAN and WILL trigger limp modes, and the symptoms are very much like the ones you are describing. you need to get your rom flashed again with those codes disabled.
+1, best answer so far.
