Greddy V-mount installed. Weird sound and no intake suction.
So I finally finished my Greddy V mount installation and it went ok but I heard a weird sound. So I went to get on the throttle with the hood open and I heard a low grumble coming from the top Greddy intake when I got on the throttle and let off but not during. I took the filter off both intakes to see if there was suction. And it's pulling air in from the bottom one. But not the top one and when I put my hand over it I can feel it actually pushing a little air out instead of intaking air. Not sure if this information helps but this is the intake that has I believe the non BOV valve feeding back into it. Everything else seems solid not overheating or anything. As always thanks for the help guys. The members on his forum continue to be amazing help and I'm truly appreciative of all the knowledge and help you guys have given me.

This actually sounds normal.
First off, do you have an air pump on the car?
To start, at idle you should only feel suction from the primary turbo. The secondary turbo is shut off with the charge control being closed (the butterfly valve in the Y-pipe) so you should get little to no air from that.
If you have an air pump, the air pump will probably be pulling filtered air from one of the intake pipes and dumping extra air it doesn't need into a pipe as well. Most likely the dump will be into the secondary pipe due to the location. That will give some air and also a funny noise - read up on the air pump "moo" to learn more.
If you'd like to verify if it's the air pump, unplug the air pump and that will shut it off.

Hey, we're all new once!
The air pump is right by the intake, it's the belt-driven accessory farthest to the passenger side. It probably has a sticker on top that says air pump as well.
It's solely for emissions reasons. You can remove it, but there's quite a bit to know about first - read up on that.
The plug is a grey 2-wire connector on top of the air pump, should be easy to find. The car may run a little rough if it's unplugged, but you can unplug it with the car running and plug it back in.
