x2 on crazy carl. Ive been drooling over that setup since he first posted about it.
My thought is it would allow a truck with added fueling and maybe some motor mods like cam, porting or lower static compression to run clean off the bottom without needing to cripple it with the AFC adjustment.
I would do your research and get a good idea of how you use the truck, before you contact him. One thing I would worry about is the fit of all that stuff. You might need a body lift to make room for the thing.
