Long story short, went Vortech SC v2 with AEM EMS2.
I had a "friend" do the work instead of a shop because I'm an idiot. Have had issues with the car since, but in a way it's been good because I've been learning a lot about doing work on my own. So I've had this car FI since August, and I''ve slowly been checking everything out as I learn about it.
Right now I have some issue with idle and when turning my steering wheel at a standstill, it'll lean out and struggle for a sec. Speaking with Joey, the conclusion was a vac leak somewhere.
I was wondering if some of the work that was done by the person that installed the supercharger is wrong or sub-optimal. I have a feeling some of it is supposed to be different, and right now my first though is the BOV plumbing. Can anyone with experience verify and please advise on how to correctly plumb this? Pictures attached.
More details if needed: tube to far left goes to FPR and the BOV. Middle tube goes down into a different line that I think ends up at the intake manifold under the throttle body? And right-most tube goes to air intake.
Who did your tuning for your kit? What’s it’s at idle now and how low does it dip when the concern happens? It could be just a simple idle adjustment in the ecu. Steering is electric so I don’t think it’s a vacuum leak. Does the same thing happen when the ac clutch engages?
The hose coming off the fpr looks like its collapsed. That's not good and would cause some erratic idle behavior id think. That line really shouldn't be Y there but run off a dedicated vac port. There should be another one in the back of the manifold that went to the air injection system. T off that instead for the BOV.

@Iyan112 Josh tuned my car, and he does phenomenal work! From start to finish he was really patient and helpful with my car, and when we tried to dial in the issue, he mentioned that it must be mechanical becuase of the circumstances surrounding when the car would lean out.
So one example is when I come home. I turn my steering wheel all the way to turn into a driveway, then reverse out a little, then park on my street. The car will lean out and try to die when I am going up the driveway a little, and again when I turn my steering wheel to reverse out. Very consistent, can reproduce every single time. Would also happen coming in to parking spots where I would have to turn my steering wheel and then reverse out.
@s2000Junky What would you recommend for an adapter and a line? I want to redo the plumbing and lines properly but I don't know sizes or adapters at all. Also would you happen to have a picture of the line that goes to the air injection system?

Sincerely appreciate all the help!
Its pretty standard size vac line which you can purchase in bulk at any auto zone/napa etc - its one size up from the smallest vac line produced. Just take a section of it in to the store with you to size it up properly, then buy 3' or 4' of it and cut to the size you need at home. Its cheap. The port im talking about is the last one on manifold closest to the firewall - you can see its a very short run maybe 3" to that air/check valve bolted ot the manifold. Its the round looking thing. Take the Y fitting from the collapsed line and use that to split off that back vac port with the short line thats there already and run the new line from there t your BOV, then replace the collapsed line with length you need. Im not saying this is for sure going to solve your problem, but from a guy looking at your engine bay from behind the computer, this is clearly not right and could be contributing and should do it anyway.
The other thing you might have an issue with is voltage to the fuel pump - if your running a bigger after market pump, they can drain voltage with the stock wiring and when you turn the steering wheel or ask for any other voltage demands from car you could be robbing fuel pressure. That collapse line to fpr may also be causing the fuel pump to work overtime. or simply causing pressure to be off what the EMS was tuned to and is fluctuating.
*Also please re orientate the coupler to your throttle body, it looks like its about to slip off the end. You can see it looks very haphazardly placed on there. And whats the threaded port hole we see on the BOV which looks like something is supposed to be there? m not familiar enough the the Vortech BOV to know, but id be suspected boost loss there if there is supposed to be some kind of plug or fitting.
Begs the question to me - Did this supposed great tuner ever look under your engine bay at the install? I wonder what else is screwy we cant see.

Might be the angle, but also check your throttle body. Looks like the charge tube not on fully on the last pic. Kinda looks like at and angle and clamp is right on the edge.

@s2000Junky Took all of your suggestions, car idles without a hitch now! It used to have little hiccups before, have not tested the steering wheel aspect of it yet but will update tomorrow when I take it for an actual drive. Definitely a much smoother feel all around. Adjusted the clamp on the throttle body, I hadn't caught that to be honest, but was a good change all around.
As for the tuner, that was Josh from here on s2ki, so it was a remote tune. There was no way for him to know what the engine bay looked like, and I had assured him prior that all was well, because that was my assumption from day 1. I will be in contact with him in a few months once I figure out how I'm going to do the work for Flex Fuel!
Something's not adding up!
