is the vdi on a s5 n/a needed to function?
im asking this becasue i am removing the emissions along with the omp and air pump and i just want to wire my 5th and 6th ports open... now i know that lots wont agree with just wiring them open but i personally dont care if they operate as i will lose what maybey 5hp below 4k? its a sacrafice im willing to make. ( i might even just remove them all together).
but onto my question what is the function of the vdi and do i really need it>? because i would prefer not to hook it up if possible.as i wont have any air pump

Its not that much of a drop from just the aux ports, but the VDI wired open also saps power.
After thinking about it its not probably 25-30 hp, I was basing that on the percentage of max power. Its still a noticeable drop, and the car feels quite sluggish below 4-5k.
On an S5 there is no real reason to remove the air pump. I would be surprised if it causes more than a 1-2 hp loss in power since all its moving is air. You already have a very efficient, reliable way of operating the aux ports and VDI, don't get rid of it.
