Those who are planning on a physical ECM swap to maintain warrantee, may want to wait and see if the Camaro's ECM has a security tamper tape on it. If I am not mistaken GM started to put these on the cars in the last couple years. SO as soon as you cut or peel the tape the warrantee gets voided. Maybe someone more tune savvy can answer this.

Also, if you go for a Handheld programmer, you can download the factory tune and store it as a digital file and re-upload it in the future if need be. The good thing with this technique is each time you add a mod you can work with the tuner to get a new tune, if one is developed for the mod you purchase.
