Hello all,
I have a few questions about some of my vacuume lines on my 2015 evo fe. I bought the car almost 2 years ago and have had issues with it since. Right now I'm throwing a lean code that I think was my maf. I cleaned it and the intake up and the code went away(catch can ordered and otw). I have the 3 port grimmspeed boost controller. I watched how to run those on YouTube but the solenoid that has the black plug on it under the 3 port has a nipple with nothing connected. I know the brown plug solenoid was removed for the 3 port but does the black plug one go somewhere? Number 2 is the hose coming from the bpv is supposed to go into the front of the motor coming from the hardline has a tee splitting it and going back behind the boost controller that looks like a 1 port solenoid with a cable coming out of it. Is this supposed to be teed off here? All my 3 port hoses are directly to wg, turbo inlet and ets intake.

List of all mods that i know of(understand some are irrelevant but it's easier to copy and paste than to write it out)

Hose coming from bpv

This is the solenoid or whatever that the bpv tees off to

That little black box t'd into your BPV is for your boost gauge. The solenoid below your 3 port is fine its supposed to be left just like that.

 

OK hell yeah. My gauge is reading an e2 code on the afr portion of it. Online it says either a faulty sensor or bad connection so I wasn't sure if those vacuume hoses had something to do with me not getting my afr readings. It makes me feel better that that port is supposed to be left open lol. thank you for your input!
