Hello guys
I need help identifying what this hose i circled red is called and what does it do,
reason i ask is that this morning i drove my GTT on the highway and i instantly noticed a lost in power, my boost gauge shows my max boost today was only 4 PSI as before i ran 10 PSI all the time, i presume this hose is the culprit as it is teared a little bit a while ago to which i wrapped it around in that yellow sticky tape and clamped it together.
