Intake Manifold Runner Control. The rectangular box under the water pump cover (Duratec word on plastic). The IMRC, if broken will not let you run above 4 to 4.5 k rpms. I assume you know that cats mean catalytic converter (SVTs have 2 pre cats (Bank 1 firewall and Bank 2 radiator) and one main cat. In addition, EGR exhaust gas recirculation system.

Edit. Picture of EGR (UFO looking thing below Ray's finger).
