In the attach picture, I have tapped into this vacuum hose with a 3 way T for my boost gauge, greddy pressure sensor and fpr.

Now I need to tie in the J&S Safeguard unit to the same connection where my boost gauge is.

Will I still get an accurate readings using a 4 way T ?

Next time I take off the plenum, I think I will make another vacuum inlet/connection.

Thanks in advance

 

I had heard that you may not get a good reading if you have to many things running off of one vacuum line .I have my boost gauge on that line , and BOV , SS box, FMU , running off the vacuum line on the front left of the plenum

 

ACP,
Same here I have about Three things tapped off of the front left plenum. I did have four for a while and all my gauges were within spec.

ACP, it shouldnt make a difference.
