Thanks nemiro! Always good to hear your input. I know the TB increase is a great mod for our NA but was always wondering why it's not more talked about for our SRTs. Currently got DCAI, 65mm Supercharger Pulley and TCU/ECU tune. So far so good. Cooling upgrades in the future I'm thinking. Maybe ported manifolds...not quite sure how far I wanna go.
