Jestnomen has APR chipped B7. search under his name, you could find some useful info.

As Badluckaudi says, "C" valve will be the best option for now.

 

Anyone else have some first hand knowledge on the DVFSiT or the "C" valve for the 2.0T B7 A4???

 

I replaced the B with the C valve on my A3 which has the same engine as yours. As for me, the DV was accessible from under the car near the firewall area. It has 3 M5 screws which are easy to take out. It has some locktite on it so it may feel like your stripping the bolts but dont worry as it'll eventually come out.

I believe your DV is located on the passenger side and will also be accessible from underneath. However, I think the drive shaft will be in the way but it should still be doable. Since your car is a 2007, I'm pretty sure you already have the C valve.

 

So the "C" valve is mainly stock and will not increase the noise of the turbo?? Is that wrong or right?

 

Thats right. Get an intake if you want to hear louder spool/DV noise. If you are auto/tip though it will be less audiable since you dont take your foot off the gas when the gears change.

 

Well I installed one on Monday on my car and it was about 45min. The hard part was just to be able to get in and take those damn clips off. As soon as i did that it was all good. Not sure the time on a B7 since i have a B6.

 

Took me about 45 mins for the 710, then the second time i took the 710 out and in was about 25 mins. Then when i put the forge in it took about 15 mins. That all includes jacking the car up etc. I wouldnt expect a first timer to do it in less than a half hour, especially on the B7 because it doesnt sound as easy.

 

I am def really interested to see how much harder it is to install on the B7. Also to see how much louder the newer valve would make it.

 

I received DV 710N today and I will try to put it in A4 2.0t 2006.
I will tell you later after I finished.
Thanks for your help everybody. It's so wonderful to have your guy in this forums.
