Now to some this may seem like a stupid question and no doubt i am going to be made to look like tool ,but here goes.
Having recently installed my Cobb TIP and SRI i am having concerns with the performance of my BOV.
The BOV is a stock part at present. When loading up i was expecting to get the the sound of turbo spool but i cant help but think that there is a little too much "HISS" for my liking.
Curious as to whether the internal diaphragm may be faulty and causing pressure dump before the correct manifold pressure is reached.
Can this be tested, and if so, How?
