are you absolutely certain that you gapped those iridiums properly?
iridium plugs are notoriously difficult to gap without damaging them.
(for the life of me i don't know why people just don't get coppers and replace them annually.)
it only happens at wot or under hard accerlerarion. If I apply 30% throttle the car doesn't sputter but once I flat foot it, it goes down the drain.
this sounds like either 1) an open loop issue or 2) a high load ignition issue or 3) a tune issue
1) contains fuel pump, fuel filter, fuel pressure regulator, maf sensor
2) contains coil packs, plugs
3) contains some other ecu parameters/maps
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.
