help

I recently installed an banks big head waste gate, 4" mbrp exhaust, and AFE intake manifold on my 2001 7.3L. When the motor is cold i am hearing as sound almost like the waste gate is open bypassing into the exhaust but only at part throttle rolling through town. When i apply more throttle the sound goes away but then comes back when i even out back to part throttle..... after everything warms up it seems to go away, I checked everything for leaks and didn't find any. Its a woooshing sound hard to explain. Has anyone ever run into this before?

It's called an ebv doing its job. You are just fine. Thinking your mods fixed a problem you didn't know you had. Lol

Every 7.3L owner has run into that before. It is the EBPV and it is completely normal. Some guys choose to delete it, and others don't mind it.
