Stage 1 EPL engine tune and DSG tune has been successfully flashed today. EPL has awesome services, so I highly recommend them. The DSG feel so much snappier, as for the engine tune, the S4 is still going through the adaption phase so I'm not going to judge just get. As well EPL suggested I get some new plugs so I got those on order.
Next, I got my ECS Tuning Carbon Fiber Intake boot/pipe installed. This is connected to to my ported air box so it is not a true open air intake. I love the look of that carbon fiber in the engine bay. I had my daughter record this video so I apologize for the shake, I scared her a few times while revving it. From within the cabin the the supercharge whine is noticeable, but not over the top. I've heard that any new intake takes a few weeks for the sound to get louder so we will see how loud it gets.
From my 97 VW Jetta VR6, to 2001 B5 S4, and now to my 2013 B8 S4 the first thing I do is always port out my stock air box. It seem like all newer cars the air box gets bigger but the intake to allow the air into the box gets smaller. In any case I cut out about 3-4 square inches of the box on the back passenger side of the box. Also on the front side I added about 20 or so 1/4 inch wide holes. While I was in here I check the air filter but it looks like the dealer I bought it from installed as new one as it was extremely clean.
Any difference in power? No not really, but I was mainly doing this to increase the sound of the super charger as this was recommend. I can hear the super charger ever so slightly now, I still need to get a new intake boot to really increase the the sound.
