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.

You realize that was the same sentence right?

It's been posted before, add a couple degrees ignition advance, work on shift points and shift firmness...Not a whole lot to be had unfortunately...

 

[Lennart]

Messing with a gasser tune really only starts to make sense to adjust for mods you have done....like cam, heads etc.

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.
