Hey guys i have recently changed a few things on my evo: muse upper and lower icp, hallman mbc, ets 3.5 intercooler, agency power 50/50 bov, and i also did a cluch job on my own and put the fidanza 3.2 in there.

So after starting the car there is a hissing sound coming from the upper intercooler pipe area right where the bov hooks up. now i have taken that hose off and cranked on it and wiggled it and the sound never changed so im not thinging its that. what could it possibly be? and here is another thing.....When i drive the car and build some boost n let off to shift my rpms rise quit a bit and it never did that b4 i put all these parts on the car. I have gotin throttle hang twice now also.... just stressfull

thanks guys

Hey guys a lil update i took off the uicp and pressure tested it and it is leak free. i think the hiss is the sound of the air passing through the pipe.

Now for the bov im getting a lot of fluttering with it....should i tighten the spring on it?

 

if its fluttering you gota losen it a bit ^^
