High Egt's

For a while I have been watching my Edge to see what is causing a problem I've been having.
When pulling heavy, I noticed sometimes my EGT's get up to the point of setting off my alarm setting of 1200*. I've been wondering why sometimes it's been fine and then shortly in the same few minutes, it spikes. It's when the TC is locked and at high cruising speeds with slight acceleration.
After watching closer, I see that when the turbo boost hangs around 10+ psi. all is good. When the EGT's go up the boost is under 10 psi..
So when I kick into it, it eventually gets back to its normal routine.
My first though is maybe a sticking or failing VGT solenoid.
Thanks any input.

1200º EGT's are not that hot and nothing to worry about for towing.

Yeah I know what you're saying. But I can something going on.
When I'm on flat ground and accelerating slightly it goes back and forth between this situation I'm seeing.
I'm going to try pulling out the VGT solenoid to see if it looks ok. Do these get sooted up?

A leak before the turbo can give high exhaust temps.
