Hello everyone,
I recently purchased a 99 GS-T (stock) and have purchased some parts for it.
Here's a list of mods I've purchased:
Injen intake
Ported exhaust manifold
VRSF fmic
TurboXS BC(IR boost solenoid on the way to replace)
HKS BOV (venting to atmosphere)
Evo3 16G
Full 3" exhaust o2 housing back
ECM Link V3 full
About to be installed:
Walbro 255
Aeromotive a1000 afpr
650cc injectors
GM Maf w/ harness for ecmlink
Innovative MTX-L
Now here's my problem, I've looked at the Taboo vacuum reduction and have some questions, here is the stock diagram.

Here is the original reduction:

And here is the way I believe I'm suppose to do:
The diagram lists nothing about the hoses coming off the cold air intake. (may not be vacuum?)
I know the one goes to the valve cover but the other goes somewhere under the battery.
Do I leave that one hooked up the the intake or cap it off.
The other question I have is can I simply unplug all the other vacuum lines and cap off the intake inlets? Or do I actually have to remove the components from under the hood and also install a EGR block off plate?
Sorry for posting a new thread but I've searched for a while now with nothing stating my problems due to the difference between the 2ga and 2gb's.
Thanks!

. Luckily, the previous owner had already plated the EGR, so thats one thing I didnt have to worry about.
