Do these need to be plugged? I have a gs 3 port and dont know if these should be plugged. I think ive got a boost leak cuz im only hitting 19psi and tapering to 15psi.

what tune/map are you running? and are those from the part that you are supposed to take off and not use after the install??

 

No, please review the post I listed. Those come with the replacement plug in the GS 3 Port kit. Original one is Brown not Black and the color dots on the plastic tubes are different colors.

The post talks about those tube hookups in specific.

 

right, but if you're on a stock tune, you're not going to hit higher boost regardless of which solenoid is in there, and, if your tune isn't for a 3 port, it won't work anyways.

you also need to remove the boost bill from the factory t-fittings.

one hose is pressure source, one is wastegate actuator, other just vents to atmosphere or back to intake

I'd be really careful modding an X all ***** nilly

 

Im on the stage 3 map with the cobb accessport.

 

alright, so one port goes to the wastegate actuator, one port goes to the boost/vacuum source (usually the nipple on the turbo outlet), and the other one is just open, that's where it bleeds off excess psi. You can chose to run it to the intake if you want, but that's just for emissions.



port "B" is the one you can let vent to air or intake

 

ok i read it and its hooked up correct but im just wondering if i need to plug those.

top line is connected to turbo
middle line is connected to intake
bottom line is connected to wastegate

 

yes but i have a gs ebc

 

Oh so you had a GM 3 port and went to the Grimmspeed? First post said GM 3 port.

What are you referring to for being 'plugged'? There's only three connections and it sounds like you have them all connected properly right?

 

those two nipples under my gs ebc. one has a red dot and other has a yllow dot

 

no, it's just the factory boost solenoid, it does nothing. It's only connected so the ECU doesn't throw codes, it's bypassed completely

 

ok good so do i have it hooked up correct?

top line is to the turbo
middle is to the intake
bottom is to wastegate

 

No
Top to intake
Middle to turbo
Bottom to wastegate actuator

 

damn need to switch em around. wonder if thats the reason im only boosting to 18psi
