    Looks to be, that's what I would guess at least. Looks like the generic tube that come with most boost gauge kits...

    It it blocked off? If not that's a nasty little boost/vac leak.

    The end of this tube is no blocked. It is like on photo. when i put there finger I feel little vacuum. It was same vacuum if motor runs in 1000 or 6000 rpm.
    I think when motor runs faster there must be some pressure no vacuum or not?
    During driving sometimes I hear some sound like tssssssss

    revving the engine stationary will not see you any boost still, as there is no load, so you'll still see a vacuum. try plugging it and see if it makes any difference, or install a guage on it!

    Yep, either block it off of use it for a gauge...

    Even a pipe that size will lose you a substantial amount of boost, so it defiantly needs addressing as soon as.

    That is definitely what the noises you're hearing are.... Just find a screw and wind it into the end of the pipe, bit of silicone around it, job done. :)

    Yeah it's definitley for a boost gauge, you need to plug it asap or put a guage on it.
