Hole size is fine…. You’re idling at 92kpa (key on engine off is 100) hence you either have a massive VAC leak (but since the engine runs and hit commanded, I’m going to say it’s not hitting on a eight… I’d pull Vc and look to see if anything is out of place…

Map I'll pull the intake to check the gaskets
The IAC is 150-200. It would be zero if it had a vacuum leak.
The STIT are 18%+
How much have you opened the throttle blade up?
It needs more air. I don't think I've ever drilled a bigger hole in a T/B.
We need more information on the build.

There is no activity on bank 2 oxygen sensor has no activity.
Bank 1 oxygen sensor is dead lean at idle and moves when you snap the throttle, so that one appears to be working.
Bank 2 is dead or not hooked up.

Verdad Gallardo open the throttle blade, do a TPS reset. It needs more air. Absolutely no reason to drill the TB.
Because what will happen is, you will end up drilling too big of a hole and you are fucked.
You have to open up the TB a LOT, before the voltage gets high enough to throw a DTC.
To start out, open it up 1/2 to 3/4 of a turn, do a TPS reset and see how it does. If it's still struggling. Open it another 1/2 turn and repeat.
Tuning the VE and MAF will normally require you to mess with the screw several times before it's right. Then you have to tune the BRAF after that.
and you need to fix that 02 sensor.
