I know of some reputable tuners but they mostly do Honda stuff, and most don't use easimap (hondata and emerald I think), though I don't know if that really matters tbh. The ultimate duratec engine builder/tuner (nationally AFAIK) is Hasselgren up in Berkeley (builds for formula Atlantic), but I dunno if he does "lower end" tuning or has a chassis dyno. And his rate might be insane. I would reach out to him though.
