Tuning a e46 with turbo..

Ok so I have looked over the thread and read a couple posts with people posting up turbo kits asking if this will work.. Honestly I was going to do the same thing.. After reading seems that most the kits will work! But it's the tune that is the problem. And having driven a honda for a while I understand the difference.. My question is.. Does anybody know a place that can do a tune on an E46?

Any help is great! I'm in Omaha Nebraska. Any places close. And by close I mean. Kansas City, St. Louis, Chicago, somewhere in Texas even?
