I have it in my ex - Red Blaze '04 Limited before (see pics in gallery) and I can feel it does something in the torque other than protecting my electrical system.

I'm using it now in my 2006 mustang since I seldom drive my new SRT-6 and I still hasn't installed my audio system. The tiny flashing light from the Hypervoltage system can drain your battery if you are not using your car more often.
