wrap the up pipe joints in tin foil. I bet you have a leak. they are nearly impossible to detect visually and you just did them. Also what are the egts/boost/speed when going up the hill?
one thing you can do and it will help a ton when the issue is resolved is unplug the red vac hose end on the brass cupcake on the turbo housing. Then plug the red hose end near where the other end is on a plastic nipple. You'll see 3+more boost psi on hills. Most waste gates need to be tightened but you can just remove te red tube. It was infamously called the "red tube mod"
