Hey Boss 302 guy here with a question for Shelby owners. Reason I came over here is because I thought this question was more applicable to boosted cars like the GT500. I'm running twin turbos on my Boss 302, not too many guys on the 302 side of the fence are boosted......hence I'm here. Thanks for having me.

The Boss came equipped with a JMS Power Max voltage booster. The concept of how it works isn't rocket science (although I did graduate in the bottom 25% of my high school class), but one thing has me baffled. It's got a remote control knob which apparently overrides the front panel on the Power Max. Settings on panel are 0/25/50/75/100. I got no clue what those numbers mean. I assume its related to dialing in increased voltage. Not being an electrical engineer (I'm just a stupid pilot) can somebody explain to me why you wouldn't want max voltage available all the time or under what circumstances you would dial it up if the latter wasn't true?

Thanks tons.....
