Plug And Play DPF-Friendly Module For ’13 to ’14 Ram HD's

Introducing a power-adder for the latest truck on the market isn’t as easy as it used to be. ECUs are smarter, emissions control devices are plentiful, the trucks themselves are expensive, and warranties can’t be voided. It goes without saying that companies attempting to unleash more power from a modern diesel engines have their work cut out for them. In recent years, Big Brother has also made it very clear that tampering with (or removing) emissions equipment is a big no-no. Because of this, there has been a shift in the industry toward DPF-on modifications.
With a history of making simple, plug-and-play tuning modules and pressure boxes for the aftermarket, TS Performance came up with the Stryker. It’s an injector duration module capable of varying injector pulse width and injection timing—and it’s one of the first power-adders available for 2013 and 2014 Ram trucks. The module is DPF-friendly, doesn’t shorten the life of the filter, and the company says it cuts regeneration intervals in half, meaning less diesel exhaust fluid (DEF) consumption. Staying true to TS Performance’s roots, the Stryker injector duration module installs in minutes and is untraceable. Follow along for the install and dyno results we found over at Randall’s Performance.
After that, the harnesses that connect to the Stryker Stryker injector duration module were routed along the valve cover back to the firewall, and then forward along the driver-side front fenderwell. From there, the wiring harness was connected to the Stryker module itself. TS Performance supplies zip ties to secure the harness when routing it up to the module.
When overlaying the stock dyno graph with the numbers made with the Stryker module on the truck, you can see that significant gains were made. As for horsepower: from peak to peak, 68 hp was gained at the rear wheels (2,800 rpm), but at 1,800 rpm the truck is making at least 100 more hp than it did in stock form. As for torque: 250 lb-ft was gained at 1,800 rpm—right where it matters most. On top of that, gains of at least 150 lb-ft are seen throughout the duration of the graph, not to mention that nearly 900 lb-ft was achieved when the torque curve peaked at 2,000 rpm.

Our test mule for the TS Performance Stryker module was this 2013 Ram 2500 with just 6,800 miles on the odometer. A non-H.O. model, it came with the 370hp, 800-lb-ft-rated 6.7L Cummins and the 68RFE automatic transmission. The Ram dyno’d 312 hp and 695 lb-ft in stock form.

First things first, the guys at Randall’s Performance disconnected the battery terminals and made sure the key wasn’t in the ignition. Because the Stryker module connects inline with the injector harnesses on the engine, the injector harnesses were then located and unplugged.

To make installation as simple and fool-proof as possible, TS Performance labels which plug connects to the front and rear injector harness.

The guys at Randall’s started with the rear injector harness first. It’s as easy as disconnecting the factory wiring harness and connecting the supplied harness labeled “rear” to the connector that was just released. Then they moved on to the front harness.

In order to get power to the module, the ground and power wires were connected to the driver-side battery.

Back on the rollers, the Ram picked up 4 pounds of boost under load (peaking at 33 psi), and EGT only increased by 50 degrees over stock (peaking at 1,200).

With the module mounted, the wiring harness was given a once over to make sure it was out of harm’s way and all connection points were secure. Then the truck was fired up for the first time.

We followed TS Performance’s recommendation of mounting the Stryker module on top of the fuse box (in front of the driver-side battery). However, the guys at Randall’s opted to Velcro it to the fuse box lid rather than secure it using the supplied zip ties.
