Basically a flash to your ECM (electronic control module). These cars are setup very conservative and run VERY rich. Timing, fuel mixture... For L99 the TM torque managment is a huge upgrade to when and how your transmission shifts. You can also get rid of AFM so it won't cut down to 4 cylinders.

Drivetrain warranty is basically dead with a tune. Try CAI Cold Air intake and Catback exhaust for starters if you want to keep warranty.
