i have an 2011 ls3 c6. I added z06 mufflers and am now hooking up the npp in a box with ez tap. I have everything hooked up except the vacuum line. Where is the best place to tap a vacuum line without having to hook up to the factory location on the back of the intake? Is there any reason not to tap an existing line? My kit didn't come with any instructions and I can find very little info on where to add the ez tap
Just FYI, there were two EZ Taps, one for LS2 and one for LS3. Years back, when this was new, there apparently were cases where the wrong EZ was shipped. Just sayin'.
Check these two discussions.
Look at this one first, it is for an LS3. Post 10 has pics and note that the owner says he "modified what he was sent to fit better":
