Well the good news is as with the rest of our offerings (including CTS-V STS-V XLR-V ect) our modifications are undetectable at the dealership level so warranty isnt an issue. Also we dont take the "balls out" route that many tuners do and completely eliminate torque management. We fine tune it and keep at LEAST 50% of it in to keep driveline longevity up and shift harshness down.
I've got my car shifting at light throttle just barely harder so you notice it actually shifting and I've removed that lag between shifts for the most part. At WOT it's crisp and simple but in sport mode it shifts more like a corvette
