    Best tune I have every run (LB7). Where to go from here?

    I have attached the best tune I have ever put together for my LB7. I have over 100,000 miles on this truck, all with 200+HP and bigger tunes, and this one is my favorite so far. This tune runs so smooth on the street below 70% throttle, and is a beast from 70-100%. Power comes on quick, and the Allison shifts faster and firmer. Torque Converter lockup helps ensure power makes it to the ground rather than just heating up the transmission with slip (full built trans a must). Works great with stock fuel pump if the filter is new, and no restrictive secondary filter.

    If you have time, please look it over, and give me your opinions on what I can do to make it better from here. Or if you see anything wrong overall, I would really like that feedback too.

    Sorry. I use version 2.23 because I also regularly tune a C6.
