Cool 2005 6.0L problems

Wondering if anyone has any suggestions.
My 2005 6.0L F-350 has given me fits since new. Currently has 92K miles.
I experience a Bucking or Jerking under light acceleration when towing or climbing a grade. This happens frequently and seems to be in-between shift points. If I accelerate enough for the trans to downshift the problem seems to go away but If I try to maintain my current speed this occurs along with an audible noise resembling a backfire through a carburetor on a gas engine.
Also, when pulling a hill at approx 2700 rpm maintaining approx 30 psi of boost and running about 50 mph the truck will all of a sudden lose 20 psi boost, and about 500 to 700 rpm and drop to about 25mph. This condition will last for a minute or two and then the power will kick back in and boost, RPM and MPH will begin to rise to the previous level. This happens only when pulling a grade under load.
I have taken the truck to several dealers, none of which can duplicate the problem since they wont test drive under these conditions.
Any suggestions?

The first problem is common and according to the dealer here in Reno; there is no fix. He duplicated it by putting my truck in Drive with his foot on the brake and bringing the RPMs up. Started bucking, just like it does at 41 mph uphill. Said it was dumping excess turbo pressure. The other problem is unknown to me and I hope I don't catch it.

I had the exact same problem with my 2004 6.0. took it to the dealer they cleaned the EGR valve. runs fine now. I originally thought there was a problem with the tranny, but dealer tech said right away it was the EGR.
