evo boosting only 10 psi after vac hose changed
Hey guys so my evo vi had a boost cut and it turned out the vac hose from my wastegate actuator to the t fitting that goes to turbo was singed from the fan shroud. I replaced the hose and no more boost cut but now only getting 10 psi When i was getting 20-24 psi before... do i need a certain hose? ? Thanks

Did you replaced with OEM or just a vac hose?

I believe the OEM has a pill inside the hose.
