Pics of the engine bay would help, possibly a vacuum line you didn't hook back up properly?

What does your boost gauge say? If no boost gauge, why did you bother trying to hook up a MBC?

Put the MBC on, and leave the stock controller plugged in. Just put the small hose on the ends of the stock controller or cap them off and you should be good.

There is no stock boost controller on our Evos. You must be refering to the factory boost control solenoid aka BCS.

Bov
I know how to read and directions and hook it up and yes i had a gauge, gauge read negative 24 at idle. That normal?

Now on bov, I hooked it back up like it was, two lines of bcs then one runs to air intake and other down to a T by wastegate then one to wg then other is pos line to turbo. then bov is hooked like it always was.

Bov
Is it possible that the bov just sucks and would stop making the noise just cuz?

How much boost are you pushing under load hooked up to the stock BCS?

I am not sure what you mean. at idle boost reads negative 24 or so, and bov is hooked up right so is it possible its just not making the sound anymore because its just not?

How much boost are you seeing at full throttle? That's what he wanted to know

What we're trying to find out is how much boost you are getting when you get on it? What is your full boost reading at wide open throttle?
