that isn't a boost leak dude, and if it was unmetered air getting in you'd have a fuel trim fault code for lean running

that looks like a meaty air line, what pressure were you putting in and where was it blocked off?

I may be well off here but if there is positive pressure in the Turbo Inlet Pipe how would it suck in air from a normal pressure atmosphere?
Does the pressure of say 15psi not relate to the the manifold side of the compressor wheel? As such would the pipe not be okay in actual driving?

10 psi thats a regulator the airline is going into it, and I do have fuel trim codes, blocked off at throtte valve inlet (hose from the i/c)  :smiley:

What about if you went for a clamp like this mate. You can get a lot more clamping on it and a bigger aria to clamp
