And I think with having a 6L80 you don't need to shift high anyway cause if you shift at 6k you land right around 4k with each shift and that's a great place to land in the next gear. Maybe take it out to 6500 and land at 4500..

My total tune was half that, but I'm long term friends with my tuner too.
