What is really interesting is your dealer didn't void your power train warranty for having the speedbrake (remember it is a tuner).
Federal law states. the manufactor can't just void your warranty for after market products. they have to prove the after market product caused the problem with the factory componets.

Plenty have had this happen. Do some searches. If there is a powertrain warranty claim gm request an ECM tcm snapshot and can tell immediately if a tuner was used and warranty is denied. AFAIK all manufacturers are doing this.
