RPM Motorsports has developed a catalog of bolt-on aftermarket performance parts & custom ECU tuning for the 2015+ Chrysler 200 equipped with the 3.6L Pentastar V6 engine. In factory form, the 3.6L produces just under 300 horsepower, but with some simple modifications combined with Engine and Transmission recalibrations, you can increase the power output of the engine and shift performance of the 9-Speed ZF 9HP transmission to improve acceleration and optimize the shift schedule to shorten time between gears and set better RPM shift points to keep you in the powerband between WOT shifts.
