Easy, slam the VVT shut under low load conditions causing the turbo to spin at a much higher RPM than what most guys call for in their tunes.

oh and then when they start to give it load it will open

im also assuming this can only be done on 6.7s

Yes thats how I suspect they are doing it. And yes you need a VVT turbo to manipulate it like that.

Interesting, kinda cool feature to discover complete waste tho. Thanks for answering so fast.

All that is, is the vanes closing up a bunch at low tq lower-mid rpm range and then opening back up again...

I made an "auto eb" at high idle doing something similar. The joys of a VGT

I wish i could make a none VGT do it. Not a priority just something to have fun with.

If you want a loud non VGT then cut in a larger turbine wheel into your 351cw.

I rather leave the turbo alone, if i could tune it in a 5.9 i would just to give it a shot but I dont care enough it modify my turbo
