i notice you have both the Spintbooster and the Superchips tuner . After purchasing these [ overly & unnecessaril...y ] hig-priced goodies , do you stand behind them as cost justified? I am on the cusp and have the 3.8 in my '11 built not unlike yours. You have those and I seek some opinion from an owner, having 'mental noted' to myself and probably on evernote, to ask the first jkowner that I ran across that had these 'boosts' and I would ask if you think they are worth it/ do what they state that they can ....thnx
