Ok. I know that you've already installed a clean filter [so I will not ask that questions. However, some factory filter housings had a secondary fitler built in, it is usually round (a little smaller diameter than the regular air filter) and has a metal screen, plus other filter material in it. If your truck has this, it could be clogged causing the choking problem you have.
If this is not the case, look into the snorkle of the air cleaner housing to see it the little door inside of it is obstructing airflow into the housing.
Finally, when the housing is installed, before you put the top on it, look to see if it obstructs the small hole in the from of the throttle body the one you showed me on the picture. Let me know how it goes. Thanks
