not yet truck is not running right
Been following you post, nice of you to share info. I have some questions for you that might help out. What's your boost numbers? if boost doesn't build all the way up then you are losing air. Something you can try is to wrap the pipe connections with a piece of aluminum foil sercure air tight at both ends take for run and see if aluminum foil popped, both hot and cold side. The howling actually sounds normal to me, had a turbo mustang that sound same, it whistled on way up on boost and when I let off it would howl. Almost sounded like I had my own cheering section, I got on car ran real hard then backed off of it and you would hear wooooooooooooo. Hope that helps out a little.
