Hey Guys,

New to this forum but on my 3rd GTP. This one is stock besides the K&N setup I installed yesterday and the 160 t-stat. Looking to do some healthy mods down the road!

My question is in regards to the vacuum/boost line located towards the inlet side of the blower. The small one between the master cylinder vacuum line and the boost bypass valve line. What does this lead to? Does the ECU read from this? Does the boost gauge on the dash read from this? Why do some owners cap that off and eliminate that line?

Thanks for the help!

Glad to join the forum
