Cobb Tuning Boost Leak?

Ok well, this DV is fine and shouldn’t be the problem unless the hoses are torn or loose somewhere. You have to trace the intake hoses and clamps all the way to the turbo, then check turbo outlet pipe to the intercooler and then the charge pipe to the engine (throttle). Do you have any upgraded turbo piping after the turbo? Main thing is check for boost leaks within that whole system. If you’ve never touched them I wold focus on the DV set up and make sure everything is tight. Also how many miles are you at and have you or someone been doing the necessary services accordingly?
