heres the question..

 

have an ATR blow off valve mounted on side of intercooler(aftermarket). and it doesnt release pressure, or atleast sound like it ,when throttle is released. you always just hear the turbo flutter through air filter. has anyone used one and maybe have an answer?!

 

it is a low 10's street car.

is the valve adjustable? You might also want to check the line going to it, if it is mounted in a tight spot sometimes the line can crimp and you not notice it initially. Also make sure the line is tapped at a good source for vacuume and boost ie not before the tb or after a check valve.

the screw is set at thirteen to fifteen from factory. and the instructions say to get the line from the turbine pressure. it seems to be a reverse style set up compared to a normal blow off. i think they bought the wrong one. but we cant find any help. the company doesnt have any tech help anymore. we did have it from a vacuum line before. im just really confused and cant get them to buy a new one that we can put on the intake pipe.
