Boost

Wierd sound from truck when boost apply.
Sounds like the air filter is innside the truck
Sounds like the pressure is leaking out.
I run with Datamaster the pressure is abouth 14,5 psi at WOT
I got a Auto Meter turbo gauge and its reading 14.5 psi at WOT

Any tips

External wastegate needs a higher boost pressure spring in it (IF you are running an EWG) :dunno:

Re: Boost

Check the section that connects the intercooler and the throttle body. Also, the hose that comes off the turbo to the IC. Look for visible holes/rips/cuts/tears.

Re: Boost

Just a thought...has your air filter been moved to near the passenger side fender, where the puke tank used to be? If so, it is normal to hear intake noise/turbo whine inside the truck. The fender pipes the sound down into the passenger side footwell and right into the cabin.
I would still do the pressure test as recommended, to be sure.

The air filter&alu tube is RPM style puke tank possision so its possible.

New turbo to intercooler hose,connection intercooler - trottle body looks ok

Under the trottle body is two alu tubes (idle speed motor) thats is open inn the trottle body's inntake side

No need to worry with those.... those are for the coolant lines on F/Y bodies.

Throttle body shaft will always leak some air, usually not large enough to make a difference. You can get an aftermarket throttle body from Professional Products.

Once you open the throttle blades, you have tons of way for air to escape.... well, 6 of them anyways.

There is a big round nipple on the back of the TB that should be blocked off.
