Turbo is acting weird!

As I run down the highway at approx 1800 rpm my vgt is around 45 and I'm making about 4-5 lbs of boost on my scanguage. Then with no other input it will go to a vgt of 60-65 and from 10 to 18 lbs of boost. When it happens you can feel the truck loose power and when it goes back to normal you can feel the power come back. This happens at no set intervals and can run either way for any amount of time. Sometimes its for 30 sec and other times it may last 45 min.
Any insight or suggestions would be much appreciated!
Thanks.

Also it doesn't seem to matter which tune I'm running. Srl or loony or even stock. It is not so noticeable in stock setting.

The best place to start is find a driveway mechanic buddy that has a scan tool and have him hook it up. He will probably find there are some check engine codes in the computer. I just went through this with mine. Mine ended up being the exhaust back pressure sensor. Do this and post back results

It ended up being the ebp causing the issue. The wire going to the plug was broken internally. Made it a little hard to find. Up and running properly now.
Thanks all!
