Hey guys! Planning to get Roush CAI (CARB) for my 2017 FoST soon.

Some of the videos do flutter and some do not. It says from CJPony no tuning required. My question is, is fluttering good or normal/safe to your turbo or engine?

Can someone explain to me why it would flutter if the answer is yes and how can I get rid of it?

thanks in adv

The flutter has to do with the bypass valve and how it's being controlled. It's happening on your car right now, you just can't hear it. If you don't want to hear the flutter, leave the stock intake on.

No tune is required, the stock intake isn’t restrictive, so changing to aftermarket is easy.
