anything over waste gate psi - stutters

[SlowWhite]

Update. I havent loaded the log yet to ecmlink.

But installed new ngk bpr7es plugs gapped to .22
Rechecked cop and use new dielectric greese.
checked the fuel pressure line
rechecked the boost control lines and wiring.

Issue still happens. However last night I noticed something and captured it on logs.

For no reason I noticed the a/f would just sit/go to 10.0 on the gauge and sit there when cruising.

So I started logging and noticed right away when this happens the ecu is showing that the boost control is activated as if im trying to accelerate when im just maintaining same throttle and vacuum.
And it would stay that way for sometime.
