May sound silly, but I hear of people using agency power Y pipe AND IPD plenum, but it looks likes it is one or the other based on the fitment of the Y pipe or Plenum...is one better than the other? I already ordered the Y Pipe in red from agency, I was looking to get plenum as well, but that doesn't look like it would work.
Yes its one or the other 🙄. Good luck on the AP Y pipe mine was a complete disaster to install it, parts didn’t fit I would expect much more for $1200 metal pipe. There billet diverted valves are on point.

I think the TCU tune is the only other performance "enhancement" I'll be doing to the car. I have an extended warranty and my dealer knows that I do the software upgrades and lets me know if anything they're doing to the car will require hooking it up to the computer so I can flash it back beforehand. Even if some of those those things you mention don't specifically violate the warranty the more stock the mechanicals look the easier it is for them to have plausible deniability should anything major ever go wrong.
And 600(ish) horsepower is more than enough to get me in trouble for now.

What is the tranny tune supposed to do?

The PDK transmission software upgrade includes 3 stages. You can pick the stage that best suits your needs or a combination based on your driving needs for street, track or a combination of both.
Stage 1*:
- Modification of shifting times (shorter shifting / gear switching times)
- Modification of rocker switch/paddle response time (shorter)
- Suspension or modification of the torque limiter
- Deactivation or modification of compulsory upshift in any mode (manual, normal, sport, sport plus)
- Deactivation of downshift on Kickdown prevented in any mode (manual, normal, sport, sport plus)
- Improved switching characteristics (i.e. no jerking, smooth transition when shifting)
- Modification of speed limit
Stage 2*:
- Modification of shift points – allowing a higher max. rotational speed (Nmax)
- Modification of the clutch pressure (no slipping clutch, especially turbo vehicles)
- Modification of switching operations to individual driving behavior
- Activating Launch Control in all modes (manual, normal, sport, sport plus)
*Additional options for Stage 1 and 2:
- Reprogramming rocker switches
- Reprogramming gear levers (direction +/-)
- Activating Launch Control for vehicles without chrono sport and chrono sport plus
Stage 3:
- Individual programming car characteristics based on any options in Stage 1 and 2
- Customized Tuning of Launch Control

Agreed - stick with IPD plenum only.
