Some background....my tuner said my turbo was dying so I replaced it with a used TD04. When I took it for a stage 2 protune, he said he can't more than 15psi out of it with the wastegate deactivated. So he said he will leave it deactivated since its not going any higher. Two weeks later I am ZERO boost so I thought I had a leak. I bought some Perrin I/C hoses thinking I may not have installed the I/C right when I replace the turbo. When I open the hood I see this:
Could this be the cause?? Either way, wtf does this hose do? I see one end goes to the intake after the MAF. Any help is appreciated. I am installing a boost gauge next Tuesday but would like my car somewhat functional before then.
