Recommendations for trans tune

[docdocgoose]

Looking for recommendations on a transmission tune on our 15 Denali XL (8 speed). On the first 1-2 shift every day it is very rough. Other than that, it shifts normal. After that, it shifts perfect the rest of the day. Who would you recommend for a trans tune to try and remedy this as much as possible.

The favorite part of my tunes is in how the transmissions operate. @BlackBearPerf has tuned 2 of my 3 trucks so far. Will be doing the 3rd soon.
