Have you ever experienced hesitation when shopping for horsepower? Is there a constant, unnerving fear in the back of your mind that you won't get what you paid for? Not able to justify the cost because you really aren't 100% positive you even want a tuned-up diesel? Or that it will make "that much difference"? Wouldn’t it put your mind at ease if you could just try it before you buy it? Well, now you can! (Read more ...)

The RFI is an advanced airflow induction built to increase the engine’s ability to breath. By replacing the restrictive stock induction, RFI increases horsepower, torque, fuel efficiency, and decreases exhaust gas temperatures. By removing the stock air box, replacing it with a metal heat shield, and using a conical air filter you can maximize the air filter cleaning area and allow the engine to breathe easier and produce more horsepower. All RFI inductions use a lifetime reusable 4” layer cotton gauze filter. This design, combined with deep pleats, make these filters ideal for high performance use. (Read more ...)

Bully Dog Technologies’ Rapid Flow Exhaust Systems are designed and built with absolute minimal degree angles on bends. This will create the most free flowing low back pressure system in the industry allowing the turbo to move air more freely, reducing exhaust temperatures. Dyno results have shown a significant gain in horsepower by simply switching from stock to a Rapid Flow Exhaust System. Available in 16-gauge aluminized, T-304 micro shine stainless steel or T-409 stainless steel. (Read more ...)

Bully Dog is the leader in diesel nitrous technology. The Bully Kicker kit gives up to 150 hp. The Dual Shot Bully Kicker kit gives up to a 200 hp shot, complete with throttle switches, a pressure switch and high performance solenoids. The Dual Shot Racing kit blows away the competition with a huge gain of up to 250 hp. All nitrous kits are dry kits. Nitrous injection must be matched with diesel fuel input to show proper gains.

These transmission kits increase line pressure in the transmission, which reduces torque converter and transmission clutch slippage and improves shifting. Easy to install using basic hand tools. Bully Dog’s shift enhancers improve shift and line pressure while reducing slipping and lowering heat. The end result is firmer, quicker shifts which vastly improves the driving experience and longevity of the transmission by lowering transmission temperatures. The shift enhancer will fit in all E40D and the 4R100 transmissions.
