The 1200-cfm Pro-Ram system (part No. 77143, $3100) is based off of a high-flow, single-plane intake manifold. The nice aspect of the Pro-Ram is that it comes ready to rock, with 36-pound injectors, fuel rails, billet throttle body, wiring harness and ECU, and a high-flow fuel pump. As you can see, the idle air, intake air, coolant temp, and throttle position sensors are already installed. The TransGo shift kit (part No. 4L60EPSK) retails for just $171 and is money well spent as it offers enhancements in both performance and longevity.
