The '98 1/2 to '02 24-valve Cummins engines equipped with the Bosch VP44 injection pump don't always get as much love as their predecessor, the P-pumped 12-valve. But one benefit that the 24-valve has over the mechanically injected engines, is the fact that it is electronically controlled. This means you can increase its power output by simply plugging in a performance module. While many aftermarket companies simply picked up and moved on when more advanced common-rail engines were released, TS Performance has stuck with VP44 owners. Its latest product for the 24-valve Cummins, the MVP, offers gains up to 100 hp, and mileage improvements of up to 2-3 mpg.
We recently got our hands on an '02 Dodge Ram five-speed dualie and had some downtime on a recent trip to Illinois. With one quick call to the guys at TS Performance, they shipped us their new MVP to try out. Here's how the install went, along with the dyno numbers we made at Scheid Diesel, and our post-install driving impressions. DP
 Included with TS Performance's...  Included with TS Performance's MVP module is an in-cab adjustable switch and wire, Velcro for mounting the module under the hood, manifold absolute pressure sensor (MAP) adapter, and a controller area network (CAN) connector. Both the MAP sensor line and the CAN connector wire tie into a single connection line that plugs into the module itself. |  First, we located and removed...  First, we located and removed the three-pin CAN plug, which is on the driver side of the engine (in front of the fuel filter housing), also known as a "false plug". Then we inserted the TS Performance CAN connector, which intercepts the signal sent from the ECM to the injection pump, allowing the module to re-map both the timing and fueling curves of the engine. |  Next, we disconnected the...  Next, we disconnected the MAP sensor plug, which is on the driver side of the engine (behind the fuel filter housing), and attached the MVP wiring harness inline, between the MAP sensor and the factory wiring. Hijacking the MAP sensor information prevents the ECM from throwing an overboost code, effectively fooling the truck's computer. |

We mounted it using the Velcro that TS Performance supplied us with. |  Next, we disconnected the...  Next, we disconnected the switch dial from the switch wiring in order to feed it through the engine bay and into the cab. We fed the wire through the firewall using an existing hole, so no drilling was required. |  Once enough excess wire was...  Once enough excess wire was pulled into the cab, we connected the switch line to the module. |
