From what i've searched there are two options included on the Osiris tuning, that would enhance the driveability of the 7AT:
1-Throttle mapping: Being able to eliminate the throttle lag, and provide a better "Feel" to throttle reponse
This is a Great Thread on the Topic
2-Tranny Torque Map: Provides the ability to adjust line pressure and shifting speeds, as You add more power to your car the ECU stock torque estimates are way off, by adjusting this parameters You can make the transmission shift smoother and faster and complement your mods.
On this second feature I tried searching for more information but very little came up, any of you guys have played with this option and bumped up values according to different power levels?
