[QUOTE="HardofWhoring, post: 8828113, member: 674149"] That voltage is externally regulated by the ECU, or PCM, or one of control modules. It specifically runs at lower voltage (about 11v is common), so your alternator can run less often, which in turn is less drag, and gives better highway mpg. Just guessing, but you might be able to change it with tuning. Have you asked on the GM forums? [/QUOTE]
