This news may interest some here.. I've spoke to Magnacharger and found out they are working on a supercharger for the 07. It is still in the testing phase but in a few months they will know more. They still have some work to do on the calibration. I have a 04 Silverado SS with their supercharger and the extra 120hp makes is much more fun to drive. I can only imagine what it will do to the 07 Escalades..
