Well, its been busy to say the least, hopefully someone is still interested in helping me.
Were are here to help. So far there is a chance the one bank has an issue. It looks off but you will only know if you log… You need to log the car over a rpm range of 800-2500 you need to watch the range and see how it folows

Sorry I just got your pm. The range is very off from bank to bank. See if your down pipes are clogged or bad. Then check for vac leaks
I am chasing a vacuum leak. I checked the intake manifold bolts and they were all out of spec, over torqued and under torqued. I even broke the ball end off my socket trying to loosen them. So I decided to replace the intake manifold gaskets and found a few troubling things.
One were does this go, and what does it belong to?
http://www.audizine.com/gallery/data/500/20160319_225005.jpg
Broken fuel injector seals. Would that cause a leak?
http://www.audizine.com/gallery/data/500/medium/20160319_223335.jpg
One of them had rubber o-ring on it, while none of the others did.
http://www.audizine.com/gallery/data/500/medium/20160319_223244.jpg
The top picture goes to the intake air box flap door.
As for the injectors those actually look ok but obviously not perfect. There is a chance that they could have been damaged on removal as most of them that I have seen get damaged on removal. Over all they dont look too bad I dont think they would be enough to cause a leak.
As for the seals look in the ports for the seals. They should still be in there stuck on the walls. You really want to make sure you can find all of them. You dont want them going back into the motor.
If it’s near the front driver’s side of the car, then it could be for a vacuum reservoir. These sometimes get disconnected while the car is being put in “service mode”. They are fine vac lines like the one in your picture. The C5 platform vacuum reservoir looks like this:
http://audirevolution.net/addons/albums/images/924314503.jpg
Even if the line in your picture is not the vac line that is going to a vac reservoir, then one of your reservoirs may be disconnected. I’m not 100% sure, but I think there’s two vac reservoirs in the 4.2L Allroad. If you don’t see the reservoirs under the hood, then you’ll see them with the plastic front fender liners removed, while either looking from underneath, or while looking in front of the front tires. The one I’m thinking of is right in front of the driver’s side front tire. Pretty sure there’s at least one more reservoir besides that one.
Problem may also be related to your intake manifold runner control (“IMRC”). IMRC is the vacuum related delivery of air, in proper amounts, to the engine. Problems with IMRC show themselves as running rough at certain points in rpm range, loss of power at certain parts of rpm range, error codes of running lean, etc. It may be your issue. I’m actually posting a write up on IMRC today regarding C5 platform cars, so maybe that’ll help you zero in on the problem. When you pinpoint the problem, please tell us what it is.
Oh, and for whatever it’s worth, the 4.2L Allroad (engine code BAS) is not a B6/B7 S4 platform car. It’s a C5 A6 platform. Just a heads up that my IMRC write up will be in the A6/S6 section of the forum. There are many different 4.2L V8 Audi engines.
But for most intents and purposes it is closer to a b6/7 s4 4.2 than a c5 4.2
That is the reason I’m here and not there. 
I agree. The C5 AR 4.2 and B6/7 S4 are very extremely similar. It may be two different chassis but the engine is basically the same.
In the picture above it looks like that vacuum hose is between the oil filter and the back of the intake manifold. The T fitting for the secondary air injection is connected so that is a good sign. Can you take more pictures of the area around the intake manifold?

I hope these help
The line from the fuel regulator is going into the rear of the intake manifold, the lines from the kombi valves is going to the front of the block. All of them look newish, and where the lines connect to the kombi valves there is not a clamp as I have seen on my 2.7.
not quite sure why I kept typing kombi instead of Combi or EGR
i think we all know what your talking about.
The fuel reg line needs to go from the reg to the intake. That is how the car knows the fuel pressure needs to rise.
As for the SAI valves or combi valves thats right too. They need to connect to a Y and then go to the front of the motor to the solenoid that controls them to open if its cold enough
Still no improvement 
I think it’s time to have a tech look at the car (I have no idea where that money is going to come from).
Is there a significant improvement in going from the C5 5 speed from the 2.7 (poor torque converters) that is on my 4.2, to a B6/B7 S4 6 speed? JHM states its possible. If I am going to continue shoveling cash into the car moving it closer to the performance of the B6/7 S4 would be of interest to me.
Did you trace the line on the fuel reg back to its original spot on the front of the car for vac. If that regulator vac line isnt right the fuel pressure isnt going to rise right and your car is going to fall on its face and loose power.
Those factory lines can crack easy and cause a lot of issues. Sounds like your finding out each step of the way that there are a few issues. Vac lines are usually a big cause of most headaches.
As for the JHM 6 speed conversion. Its a sweet deal. putting a manual in your car espically the new 6 speed will really help make the car much more fun. The old 2.7 6 speed transmission swaps people use to do were just junk that 6 speed transmission just sucks and its espically sucks for the NA 4.2
It looks like your on the right path it just takes time when your tracking down all these bugs.
Justin, I wonder if he is interested in the 6spd tip from the B6/7? I think it can be done but I preferred the manual swap option.
I certainly am a proponent of the b6/7 0A3 6mt swap. I love rowing through the gears in mine.
The wife also needs to drive it, with three kids in the car an auto/tip is the only option for us. When I want to shift gears I take the HD out and hammer through them with my left foot!
I am interested in the 6-speed tip and curious as to “those in the know” opinions of them.
