are you looking to add performance parts or just keep it stock and make adjustments that way?

Id like to keep it stock, and tweak it that way if possible

Im with Luke... Smarty Junior and a exhaust will help you out. Unless you want the stock exhaust then just do the smarty junior

Thanks guys, I appreciate the advice,
