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.
