I installed a blowoff valve today , i hooked it up on the pipe that runs to the intercooler to the TB . I also ran a vac line to a tee in the line that supplies my vac block with vac it comes from the intake manifold. It is hooked up before the one way valve , so is it going to be in a vac or under boost , i dont get how the vac lines work . It seems to be sucking air when i rev the motor and blowing it out when i stop reving it. it seems to be blow off in the air filter still , i cant even hear the blow off if i have it hooked up right.
any help would be great
