Just interested in more tuning options
I already have Giac chip, and K&N filters
What max HP can you squeeze without changing turbos?
What will be the gain if I do high flow cats?
And is it worth to change pulleys to a light weight ones?
What max HP can you get without changing turbos?

K/N filters -30hp
Max hp w/o turbo upgrade 520hp
Cats +15
NO

but giac itself promises 520 how come total 520

Yeah, if you run the K/N long enough your MAFs will be toast.
Toast MAFs= -30hp
The rest the search engine can find.
Only way to know for sure is dyno, dyno, dyno some more.
Or go to the 1/4 mile drags and get some trap speeds. Plug the trap speeds into some hp calcs.
K&N's on the 6 are a waste of time. ITGs are the way forward.
I think 520 is a good estimate. There is a car over here that ran 535 on standard turbo's, but it had 3"milltek DP's with no cats and a custom map that was done on the rollers.
As far as I know, mine over here )according to the guy who rollingroaded the 535hp one) running 510 is the second best he has seen. But think I could probably get more from a bit more timkering....
So fast, it will re-arrange yer trousers!!
Do not believe evrything you are told.........

I got another question, if not for the tranny, then what could the motor do?
Moocher, where can you get the itg filters for the beast?
JD engineering tuned an RS6 with stock turbo's that now has +-600hp.
I personally think that the RS6 with a good tuner ie custom and some modifications such as those below ~580bhp is doable on 94-95ron pump, with E85 well over 600hp (~620hp) as this fuel is a perfect for the RS6 as the standard turbos run out of puff so this fuel will give the tuner the ability to tune "past" this.
Modifications:
3" Exhaust (Turbo back) - no cats
MAFLESS Tune - will give a more responsive car and also less inlet restriction which will increase boost
Intercoolers - Really need something that is more efficent rather than flow capacity
Fuel System - Twin Bosch 044 pumps and 800cc+ injectors with surge tank to allow E85
If you are after power it is either for top end or drag racing if the later the 60' is the killer to these cars due to the weight and also the ECU shutting the throttle while "stalling" the car to build boost.
If the above is done you will have a quick car that will destroy alot of cars.
FYI - A RS6 with boost controlled disabled and tune to allow this safely made a max of 1.8bar boost on standard turbos in the midrange creating a huge torque number, the standard turbo wastegates cant stay shut due to back pressure if these were upgraded 1.5bar from ~4000 to redline could be possible which would allow even more power
The standard transmission is a funny thing some hold up other dont, I recommend never giving it a hard time in D as it can get lost and try to shift to a correct gear during max torque which hurts the box, always give it a hard time in Tip or S.
A custom TCU program will also be good but not sure if anyone offers these.
Just my 2 cents
K&N's are really that bad for the MAFS? Bad enough for me to get them out ASAP? Replace with ITG's?

How true indeed.
Yes, run stock until you get some ITGs
OK i just ordered 2 ITG's, should be here next week..
I've been running non-stock for like 6 months with K&Ns... how would i know if my MAF's are shot?

If you want more power, you may want to consider going with a different tune. I've seen a couple dyno sheets for GIAC tuned RS6s and both of them lost power up top compared to stock:

I'm not sure what the gains are with high flow cats, but simply gutting out the OEM pre-cats adds 10-15 HP to a tuned RS6.
You won't gain much with pulleys.

Not bad for off the top of my head
how do i know if my MAF's are toast?

You will end up flashing a CEL
Depending on the miles with the K/N you get the MAFs (dirty) and they become less accurate.
The whole tuning on both banks of our engines start with the proper g/s calc by each of the MAF sensors. You want them perfect because all of your fuel, timing and boost calcs depend on that MAF.
There in lies the rub.
