if someone writes a tune for it. just buy a hydra and have someone write you a tune or better yet go get live tuned. I believe you're in texas so you could go see tony wildman, matt at gearhead or chris at truck source
In our experience, the SCT Livewire is not the best choice for the 7.3L. We have heard of a few instances of them not working at all on the 7.3L. Most of the time we see them displaying inaccurate data. That is why we only offer them for the 6.0L, as they work just fine on those trucks.
We have the Infinity if you are interested. Check it out HERE. It will do all you are asking and more.
Contact me with any questions you may have about it.
