How long ago did you install it? The computer checks the systems constantly and after 60 miles or so it should have gone through and adjusted for the airflow already.
I'm beginning to like that body style tundra more and more when lifted. One of my fraternity brothers in college had a lifted crew cab one that sounded mean.

Seems like all the problems you had with the kit were for the lift part or the shocks which aren't really part of the level. The only thing used to level it are the keys. Shocks are always a personal preference for people and whether or not they blow all depend on your driving conditions and style.
