Well, I have pullies and about 700+watts of stereo crap so, when my lights are on and im at idle sometimes my battery gets so low that it turns of the stereo and I have to rev up the engine to get it back on. I really love my stereo and Im not taking the pullies off so I figure Ill just bump up my idle. Right now its at 600rpms which seems low to me anyways so I want to bump it up to 900-1000rpms. I dont care about the gas it cant make that big of difference. Im just wondering how do I do it? I havent looked at it at all yet but is it anything like the fox's? Just tighten a screw or what?
