24.7 is not bad depending on what portion of mixed is surface street driving. You should try banging out 100 miles of pure highway driving @ 55-65 to see what kind of mileage your car is capable of. I would not be surprised if it was over 35. If you can get over 35, that will sort of provide a number to strive for, even when you're just idling around town.
I remember getting 22 mpg no matter what I did back right when I got the car. After doing very minor tune up stuff, I was able to get mid 20s. By playing with driving style, I haven't had a tank under 30 mpg for over a year. I'm not suggesting that my driving style is to be emulated, but that the car is to be applauded for its capacity of excellent efficiency.
Just remember to never ever touch the brakes. It's obviously harder in an automatic, but attempt to engine brake at all costs. Better yet, predict when you need to slow down and just drive slower to avoid braking at all.
x2 on emissions, I just barely passed on my last test. I'm running a dying magnaflow cat that's forcing think about buying a new OEM cat. Don't want to part with 650 bucks quite yet.
The charcoal canister is a filter system for gasoline fumes so that they aren't vented to the atmosphere. The charcoal adsorbs the fumes and in some systems, those fumes are even called on later when the ECU deems appropriate. How it would affect mileage, I don't know. I would expect effects to be minimal.
When you do the H23 plenum swap, clean out your EGR ports. Wed3k has a great DIY and I wrote about it in my Member's Ride page.
LOL yeah I've thought about designing an underbody tray as well. EcoModder mentions it.

It'd be a fun project, although I would expect results to be limited to mental satisfaction rather than MPG. Getting into aerodynamic mods is obviously tricky without a model and wind tunnel. That being said the MPGuino has a function where it can sort of determine coefficient of drag based on coasting acceleration on a slope. That could help greatly with the design process.
Honestly I have very little experience with the dual butterflies on the A6/H23 intake manifolds. Your guess is as good as mine as to that problem. There is also an IAT (intake air temperature) sensor on the side of the intake manifold, in the first cylinder runner. You named all the other components.
Your jumping rpm produces no CEL, right?

the guy gave me a discount because i bought so much haha
so i thought ahead and bought some spare curtains. also got some cushions and other JP stuffffff
), ET falling off his bike, and some solid snake-y pajamas. FREEDOM OF MOVEMENT, YO!
