I have just had the carbonio cold air intake fitted to my 07 S3, and after driving it for 2 days i cant work out if it has reduced the cars power or just made it feel smoother i.e. reducing turbo lag.
I have also previously had the forge diverter valve fitted which you could feel instant results. When i put my foot down now it doesnt seem as aggresive when the turbo kicks in, but at the same time doesnt feel any slower, could this be an increase in lower end torque in that you dont get the lag to turbo kick in the back as much?
Also, you do hear of cars being down on power after an air intake has been fitted, i was just curious to as what it is that reduces power if the intake has been modified to give improvements?
