i recently installed a egr delete kit on a 6.0 in a 2005 f350 and now have air rushing at the turbo. when the vgt is unhooked it goes away. what can cause this headache

Does it sound like a hissing sound? Does it affect the way it works? Heres a for you.

what can i do to correct this issue

Have you checked all of your boots from the turbo to the intercooler ??? and check the wiring to the VGT you might have broken a wire ????

[draper]

i've checked the boots and and they look good and are sealed. i have voltage in the wires. i even tryed another vgt and get the same results. what else can i try to correct it

You may want to check that all of the intake bolts are tight and that the intake is flat and sealed against the block, it definately sounds like ya are sucking air somewhere.

I would still spray the boots with soapy water. You could have a small crack.

i'm going to check over everything again and i'll get back with my findings shortly....
