I recently purchased another srt4 about two weeks ago. It’s a 2004 with 122k miles. It’s completely stock and I’m the second owner. The car has no check engine lights nor any codes so far. It drives normal. Although i noticed at WOT the psi on the boost gauge reads kinda low between 10-12psi (I took the dash off and recalibrated the original boost gauge). So that being said today I had some free time and started to really thoroughly check everything out in the engine bay. Making sure there were no broken lines or anything of that nature. As i was doing so i noticed this on the cold side of the soft piping. The normal red line that’s on there but next to it was a capped off white line. I did my searching and couldn’t really find anything about it or like it. Does anyone know what this could of been for, why it was there, or where it went to?? Possibly just to cap that rubber elbow since it was two holes? Sorry in advance if this was a dumb question.
Here’s some pics of it (first pic):

Oh and also. The two 90s connected to the bottom of #1 and #2 solenoid. Do you normally leave those as is or cap them off?

Sorry for double image posting.
Looks like that white hose went to the TIP sensor. That was another MAP sensor that should be inside the driver's side fender in front of the fuse box.

Now worries. Hmm alright… I’m a little confused now. The way the white line is now on the car, it’s going from the #1 solenoid to the bottom of the sensor that’s by the fuse box. Should that white line even be next to the red one that’s on the soft pipping? Or is it just completely random it being there?

Modern Performance has some better images of the vacuum lines.

I do not see any dual-line 90 deg fittings. (the red hard line is on one 90 deg fitting and the white hard line is on another). The red line is the only one going to the cold side tubing which goes from the intercooler to the throttle body.

the red line goes to the upper pressure pipe what you have shown. No idea why there is a white plastic line coming out of that elbow, that is not factory at all. As you can see in the picture above that retro posted, just the red line goes to the upper pressure pipe.

Do a boost leak test to the car.

Instead of making another thread i figured i would just ask and post this here.

So i currently looking into purchasing another Srt4. From the pics i can tell it’s a stage 2 with turbo toys. Only thing is in the engine bay picture i see there’s no 3 bar map sensor (or any sensor really) on the intake manifold. Any idea what this could mean?

Follow the hose. That's normally where the MAP sensor is installed. Any CEL's?
Is that common though? Usually it’s right there on top of the manifold. I haven’t checked out the car in person yet but i will soon. The guy lives 4 hrs away so it’s not to close…

That is the spot where it would normally be located. I could not tell you how the car is setup without being provided more information or access to the vehicle. Sounds like a red flag though.

Yeah it’s kinda odd. It’s a low mileage car too so weird that it’s like that…
