What kind of tune are you looking for? More than likely you will have to modify it the your needs anyways so purchasing a wideband O2 is needed if you are serioous about what you are doing.
ls1tech.com and performancetrucks.net should answer many of the questions you might have.

Are you using your own software? HP tuners has a Tune repository. If your looking for a tuner try Zippy ( he's on Performancetrucks.net , zippyperformance.com) or Try Nelsonperformance.com -2 of the best tuners out there for sure.
