Hey guys just wondering if I could T off my boost gauge with the EGR system? Thanks ahead of time for the help.

I would say just T into any of the lines off the intake Mani. Its too easy to cut one of the vacuum lines and T it to your Guage.

Tee it off of the nipple on your throttle body.

I recommend teeing off the afpr lines and routing the line through the boot for the steering column. If you do this you may want to zip tie the line to a harness underneath the steering wheel so it doesnt get in the way of the pedals if its too long. I can help with any electrical wiring too since i basicly had to figure it out on my own for a gauge pillar so just ask and i can take pics too.

Ok thanks guys I think ill run it to the throttle body I tried the egr and i was having negative boost somehow.

Are you sure that wasn't vacuum? How much psi are you running just curious

 

[eclipse420ags]

8 psi, the boost guage is brand new so i know its good. Just didnt understand why it was going negative.

 

[Ruie]

It will be negative because of vacuum. At idle it should be negative always. If it isn't, you tapped into something that doesn't give correct vacuum readings, which is not good.

For ex. On my 4g63t it sits at -18 at idle

Wow mines at -13 do I have a vacuum leak? Anyway I T'd mine to the red lined vacuum line on the in take manifold

 

[eclipse420ags]

I switched to the throttle body hose and when at full boost it just said -10(10 vacuum whatever). Is that major boost leak somewhere? I still here the big whoosh out of the BOV.

Idle at 19 vacuum

Get a vid of the car doing a WOT pull from the out side and one of your gauge.

I have mine hooked up to the throttle body and works fine. Is it on the "p" port? You can let it have its own line to the intake. Or T it with the fpr.

mines t'd off the fps, is that bad? idk it works fine

 

[eclipse420ags]

This may be a stupid question but the boost will still recognize boost when in neutral right(have mine on jacks right now).

 

[mikeymike1]

It should read vacum at idle and will read boost when the motor is under a load.

 

[eclipse420ags]

So what your saying is I can rev it in neutral to red line and boost still wont register?

 

[DCGuerrette89]

wen i rev my car to about 5000 in nutral i read 0psi
at idle i read -11
and mines stright off the manifold

 

[dsmvenge]

I have mine tee d in with my afpr and it works fine -19 at idle and boost all the way to 23 like it should. since im at 23 psi on my boost control

Ok thanks guys getting my car off jacks tomorrow I'll have an update then.
