TS Performance Power Play MP-8 modules are the perfect choice for towing and fuel economy! These modules boast a plug-and-play design that does not leave fingerprints in the factory computer. Plus, the TS Performance Power Play MP-8 modules offer up to 100 hp gains with Ford, Dodge, and Chevy applications and up to 50 hp gains on the Jeep Liberty CRD. Their in-cab adjustable feature and stacking ability are convenient and your fuel economy gains do not increase exhaust temperatures. Additionally, some models come with the MPD monitor. You can also expect horsepower gains for medium-duty trucks to be between 15 and 30 percent. Some people dream it--TS Performance builds it!
