Huff or Bark that is the Question.

Ok here goes.
Here's what mine does.
Check sig. for mods. hx 35/40 hybred.(40 compressor wheel in the 35 housing).
When the truck shifts from 3rd to 4th (7/8 throttle opening) while the converter is locked. The turbo is pulling Approx.40 psi,when it shifts the turbo psi drops to about 30 to 25 psi instantly with a little bounce in the neddle.
Does the same thing when it goes into lock up at 7/8 to full throttle in 3rd or 4th. Seems like it pulls the engine RPM's down quickly.Sometimes at WOT when it locks up it drops the RPM's almost 750 rpm . Yikes the sound is Really loud when it does that.
The sound ? Hmmm?
Bark or Huff?
Mines more like a cough, a dry cough,( no phlem) sorry about the visual.
It coughs about 3 or 4 times (kah , kah kah kah )The boost neddle bounces in unison with the coughing event.
The boost builds very fast right back up to 40psi and then I have to back off the throttle cuz I'm going way too fast for
So. California freeways.

Is this the "bark "?
Does this spell D E A T H for this awsome little turbo?
If this is a certain death how can I stop the Cough/Bark /Huff.
Got any Cough medicine?

thanks
SFB
