Bigger battery under the hood for starters. Maybe an Optima. You could also look at www.batcap.net for a power reserve. Also, a bigger alternator could be an option for you. www.alterstart.com has some affordable units. www.powermaxx.com has some higher end comp-level alternators also. Try and stay away from standard caps, as they are way over rated, but the link above for batcaps is WELL WORTH checking out they make an AWESOME product.
