You’ll love the off-the-line responsiveness and the 15% better fuel economy, too! The Predator Module sets your engine up to burn its existing fuel more efficiently by changing the air/fuel mixture and by altering the timing. This creates great volumes of energy at cooler operating temps, and cooler temperatures mean a longer life for your engine.

Beware of other “diesel performance chips” that produce damaging heat by over-fueling your engine. The Predator lives between your Electronic Control Unit (ECU) and the fuel injectors, so there’s no warranty-voiding reprogramming. Several units, each with different levels of performance, let you balance power and price (see description below). And, it only takes minutes to get it hooked up and the diesel performance dialed in.
