loud whistle under hood?
I have a 2007 f250 6.0 with egr delete, studs, gaskets, sct. The other day i was driving to the beach and started to hear a loud whistle or whine from under the hood.so i pulled over but it stopped. Only seems tohappen when foots on the pedal. A little bit of turbo lag not a huge diff. What could this be? Btw i checked boots best i could didnt feel any rips.

Sometimes the boots can rip at the very edge of the clamps where you can't feel the damage, it's best to remove the boots for inspection. Usually it's the boot coming off the turbo.
Check your flex joints on the exhaust up-pipe/y-pipe. Common for the flex joints to crack. Visually look for soot on piped, firewall and surrounding area. When the motor is cool, start her up and use your hand to feel for air/exhaust leaks at the flex joints.

The y-pipe flex joints are real common, also the the y-pipe and downpipe connections to the back of the turbo are common for that if not seated properly. pretty noticeable by the eidence ofblack soot like lilpooh said earlier. but also check all turbo connections, CAC boots and all, maybe the egr valve hole, sometimes the metallic gasket wears down and blows out. Or if you have the full egr delete its an o-ring from that kit.
