Sorry I disagree
Want the fuel tables modified as well so at wot and at transitions fuel is added along with additional turbo pressure
The 5 wire LINEAR O2 sensors will trim fuel at light loads so no major degradation in fuel mileage either
Shifts are somewhat firmer so as in all the vehicles I have owned the line pressure is increased & shift points much better at light throttle & at wot
Does not skip shift anymore either
Much better than factory calibration
Not the least bit worried about transmission life or durability
Hennessy offers 600hp calibration with 3 years powertrain warranty as well

Told me they can do the same for the EXPY
Hoping to get 0-60 in the 4's without upgrading any parts
Have the 3:73 axle ratio for better acceleration
Reason I purchased the HD tow is to get that axle ratio
