Your going to need more than two little intake tornados/ silencers to pre spool the turbo. In theory you can make more power with out them since there's no restriction in the intake tubes but it doesn't do anything but make more sound.

I actually think this is true.

Those air vortex thingies to optomize/maximize fuel mixure within the intake manifold was all "snake oil" back in the day, and the principle doesn't exist as our engines are DI.

but the fact that the turbo is significantly louder without the rings, tells me, they are silencers, and so did a Diag tech who I inquired with first before removing them.

According to Stokes law they are attenuators. Therefore they attenuate sound. Take that to the area they are at, it means weakening in force or intensity. Some OP's like a lot of sound force/intensity/turbulence ! I will guess they are designed for average driving at average RPM's ranges and not for high performance applications. In a high performance application such as a Stage 2 there is a separate air path for each turbo with a balance tube between them. :>)

FWIW

I removed mine today. Little more turbo noise but thats about it.

I have been driving it for a few days now. Before I removed them there was a little lag before the turbos were spooled up, now that seems to be gone.

What lag are you talking about ??? Now this one is first

These trucks do suffer from lag at times. Simple solution is to do the gas pedal reset procedure. If the truck was misfiring (due to condensate in the intercooler), then new spark plugs gapped to .030 are needed and the intercooler should get the 1/16" weep hole.

Def would like instructions on the weep hole. Mine lags but it's only got 54k miles

Run a tank of premium through it on a good hour highway run and it will smooth out. I have to do this like every month with my city commutes.

If you read the other threads on it this video will pop up. I know I've posted it numerous times...
