Question Low Boost after sitting for 6 weeks

Guys I need help! This is the second time that this has happened to me. I work out of country for 5-6 weeks at a time. Twice now after being away for that time when I start up my truck and begin to drive it has absolutely no boost. Drove it for 3-4 miles to the bank shut it off. When I came back out it had regular boost again. This is confusing me. The truck runs awesome otherwise. It has only done it after it sits for my time away. the rest of the time I am at home it never does this. Is there something I should be doing for the short term while I am away? There are no codes, nothing so I am at a loss of even where to begin. Any help is appreciated

So after a little more reading and some internet investigation I am wondering if it is the High Pressure Turbo Actuator that is sticking thus the low boost after long periods of inactivity, should a guy give the actuator arm a few cycles back and forth to get the turbo vanes to move or am I way off track?

Before you start it up next time it sits, try moving the actuator BEFORE you turn the key on, or have an assistant cycle the key while you are watching the actuator.

WARNING:

KEEP YOUR FINGERS AWAY FROM THE VGT ACTUATOR WITH THE KEY ON. IT HAS NO CONSCIENCE AND WILL RESULT IN YOU NEEDING YOUR WIFE TO OPEN YOUR SODA CANS FOR THE REST OF YOUR LIFE IF IT CYCLES WITH YOUR FINGERS IN THE LINKAGE.
