I'm thinking about getting one... I have an 06 5.4 L w/ 3" levleing kit and a cold air intake... does anyone have some custom tunes they could tell me to input into this this or is my best bet pay 150$/HR to have the pros make a custom tune?

Get a gryphon or a sct man. Custom tunes is recommended for a cai and both make you a custom tune.

if you really want a diablo, get through their dealer and get a custom tune. Im partial to SCT since ive been running the programming for so long.
