What is this?

I just want to get a better understanding of what this sounds like, better sound at the end of the video. What would I need to eliminate it? Is it possibly turbo surge?

Are you talking about the turbo bark at the end of the video?

It happens when you are in the throttle and let off quickly.

Here is a decent explanation:

In order to get rid of it you need to have a blow off valve

Ya shouldn't bother anything. You can avoid it by just easing our of the throttle a little more. Supposedly out trucks don't really need wastegates and BoVs but if you have the money it can't hurt right? Plus I can't imagine how sweet a BoV would sound comin off 40+ psi!

A BOV would be a great upgrade being that the back pressure from the unused boost abruptly slows the turbo and in time causing bearing failure. BTW p8ntballn2 NICE TRUCK! Just pick the same up excepted it's not a King Ranch.
