Well I fucked up...

Holy mother of god. I just got my base map in and took my first test drive. Completely different car. It's scary now and 10x more responsive :p Justin IS the fucking man. Worth every penny plus a tip. I cant imagine once revisions are done how it is going to drive. It's already near perfect. Thank fellas for the words of wisdom and support. I am smiling from ear to ear. Woooohoooo!

This made me smile glad to hear you're up and running, especially enjoying the car even more. Always happy to help, let us know how the car feels once the tune is done. Zoom zoom
 
I sure will. Quick question on my 3 port routing. My boost source line (from the EBC) is currently plugged into my HTP intake by the turbo. Most diagrams I have seen show it directly plugged into the turbo. I just wanted to make sure this would be ok for the data logs/boost readings and not cause discrepancies.
 
The boost source should absolutely not be plugged into your intake that's not going to give you boost.
Typically 1 line goes to waste gate, 1 gets T into the bpv hose to intake manifold and 1 hose cows onto the intake, this is not your boost line. Diagram is from Cobb but grimspeed is the same port config

I confirmed it was definitely hooked up to the HTP intake just before the turbo. Here's another question for ya...not seeing a barb/line to hook the boost source up to on the turbo. Can I just buy a silicone coupler with a bung (the coupler that connects my turbo to the TMIC) and route my boost source line to that? Seems like it would work but I am completely new to turbo systems.

Alternative:
Install a bung on the existing coupler, thread in a barb, and route boost source there?:

Lul what? No that's not the same port 2 needs to connect to the waste gate what you're describing would be port 3.

Keep looking its there, where was the old ebcs connected to? That's what you're looking for

Will snap some pics to make it more clear. This is the current setup. (pic attached)


Was talking about taking off the line routing to intake from EBC and running that to a bung on the turbo/tmic coupler from the EBC. All good though. Think I just found the inlet...

Lmao you're killing me, that's the coolant feed for your turbo, look at the diagram I posted that's where you'll find the connection on the turbo, or you know look at a pic of a bnr turbo to see what you're looking for

Lol, look closer....under the coolant feed line at the little capped line. I roughly outlined the shape. There is a black cap on it.

Didn't even see that thought you had circled the coolant feed.
That's probably the port on the turbo that's supposed to be capped depending on how you're running it just slightly different.

@Sho I know you're good with ebcs, isn't there a way to connect a 3 port with 2 lines to turbo ( fl1 for boost ref the other waste gate) and 1 to intake?
 
This is the exact version of the s4 I have. I circle the capped part. (pic attached)

I believe that would be your boost source, my new turbo did not have the nipple on the compressor housing so we drilled a small hole for it on the housing before the turbo to intake manifold adapter.
