Default EWG Screamer Pipe Question

I have a question concerning the sound of the screamer pipe on an EWG turbo. The parts used are in my sig.

I am used to a screamer pipe being loud but releasing a smooth sound. Like the normal exhaust note just kicked up a notch. This is happening under part throttle or when the WGDC is 0.

When I am at full throttle and the wgdc is at my max setting of around 40, it sounds like someone is clanging pots and pans together. Sort of like an old car that is constantly misfiring.

Is this what is is supposed to sound like? My thought is that the gate is opening 100% then closing 100% instead of holding open at x% consistently. Is there a setting I am missing, or something to look at?

Did you forget to put the valve seat in when you installed the WG ( looks like a metal ring)? If you forgot to put that in it will sound like it's open at idle and could cause the odd sounds you are hearing under WOT.

The valve seat ring is on there. If I remember correctly the larger OD of the ring was on the turbo side and the smaller OD went into the waste gate.

Also, it seems to smooth out almost to normal when I hit rpm's closer to redline.

try running the wg directly off of spring pressure. IE: bypass the solenoid. If you still get the flutter, you know its the solenoid, if not its something in your wg.
