Welcome PushL1. Nice mods you have, don't see harnesses? Hopefully you have them or are getting them. Stock WE shocks are good, but you'll have to upgrade for better suspension to get what you want. Either the Fox RC2 Podiums, which IMO, is a great shock, or the Stage 5 Elkas, great shock, alot more money too. You already have the ECU reflash, and exhaust. Doubt there is anything under $600 for power upgrades. Since you have a '13, does it have the quicker steering mod done to it? If not, it's cheap, easy, and well worth doing. Do a search for sharper steering.
