Gen1dak will become famous soon enough

The AC turned off really doesn't drain power unless the pulley is damaged or something. If it's knocking, is it actually engaged? Disconnect all power to it. Any difference? Not much available in the tuner dept, but remember that those tuners usually increase ignition timing, which usually increases octane requirements.
