340i goals! Good stuff bro. I had the same intermittent check engine light with my CTS intake as well. I ended up taking it off and selling it cause I didn’t want to deal with it anymore lol.
@auto andrew Most of the time it’s the sealing/seals of the parts. I forgot to put a seal on my VRSF charge pipe, got a check engine light/code for ccv failure/disconnected. Installed the seal ahha no check engine light. I’m also running an AFE CAI, turnermotorsport upgraded turbo inlet. Also if you get tuned you can compensate for the additional airflow.
Gotta get a chargepipe for reliabilitys sake, if you like the turbo noise then burger motorsports makes one with a blow off valve. I just put that on mine and it sounds great
