Just wondering if I should run a Optima or a different battery now that I have installed a new MSD btm, 255lph fuel pump, an inline fuel pump, fan mod. It seems that when I have all this on my Volt guage goes way down. The alternator is definately charging it but I haven't even turned on the a/c yet and I don't want to toast my alt. So I was thinking of throwing in an Optima...
