how to check for a boost leak?

[prj]

thats what my computer shows... thats the highest its going to..
why do you think its the boost leak? maybe it turbo?

I doubt it's the turbo.
If you plant your foot in 4th gear, you should see 2.1 with the stock software. If you don't you most likely have a boost leak.
Pressurize your intake and find it...
But first make sure your wastegate is set at 0.4 bar.

1.9 what? Boost or what it shows on your computer?
The computer shows absolute pressure, so that means 0.9 bar boost.

If you are only getting that in higher gears, then you have a boost leak somewhere.

ive got 11 mm nut on there. ill check it tomorrow and will let you know what boost will i get. as today when i checked it in normall conditions it went up to 1.9

There should be a 6mm allen key screw.
If it's screwed all the way in, then that also basically means you have no boost control...

I said what to do to test it... it's not hard to find a piece of tube.

i did opened the wastegate. and the spring is stock. but what do you mean by screwed down? there is only a nut underneath the spring and its titened up
