it does it when its warm also, you will be driving and when it locks up you will cut whatever boost i have in half.

Do you have custom tunes on it and what injectors are you running?

Try taking the edge off and see if it runs right it might be defueling the truck because you have them stacked on it. These truck dont like it to well when you stack boxes. I would try that and then go from there if that dont fix it.
