I second the rosewood folks. They'll replace all the wear components and flow test them, essentially giving you a new injector for far less than what a new injector would run. You also have the option, if you want stock performance and can afford to have your truck down for a week or two, to send them your injectors and they will flow test and blueprint your injectors, replacing components as necessary to make your set operate like new, for less money than a full 8-injector rebuild (assuming some of your injectors don't need work).
Me, I'll be sending off my cores to get some stage 1 sticks. I don't feel like doing much more than tunes, 17 deg HPOP, Superduty-style electric fuel pump, and leaving my LuK single-mass flywheel stock-power clutch in place. I hear stage 2's are a bit rough on the ol' stock strength clutches.
