It sounds like theres a missing connection between the intake and the wastegate.

pretty much like the WG isnt seeing the pressure from the intake.

 

I will weld it, im sure i crack it because my truck its to low, wasteate is like 3 inches from the floor.

 

Ok i have the wastegate bov and the boost gauge on the side of my intake port. Will it matter what hose is closer to the intake port? Because i have a y from there that one line goes to the boost gauge, the other line is connect it to the T and from there i get my BOV and wastegate.

 

Don't just weld it, weld a flat piece along both pieces to tie them together. Looks like the stainless is brittle and the flat strap-type piece will ensure the welds don't come apart again.

 

Did the wastegate eat the road causing both the crack and it to no longer work properly? Just an idea.
