Hose To Boost Controller

[Damo]

Just wondering why this hose is t'ed into my boost controller. It is tapped off a hose that is about 1 inch in diameter that runs off the intake pipe between the AFM and turbo. The hose that is 1 inch in diameter runs all the way up to the pressure relief valve near the intake manifold.

the hose in question is circled in yellow. the blue one goes to the wastegate and the red hose runs up to the intake manifold.

I am wondering about this cause i would expect this hose being hooked up to interfere with the pressure that the wastegate is seeing and hence may be causing boost spiking or turbo lag etc..

from my understand, the yellow hoses is connected into the air intake for the turbo, correct?

The reason for this is to give a more accuarted boost setting. you get the one reading from the intak manifold another from the turbo intake.

i have seen this setup uses many times, so i dont think it is causing ur spiking problem
