Bully Dog Mechanical Upgrades
Bully Dog Fuel Injectors: High horsepower injectors for off-highway use
 Experience high horsepower gains for the Dodge 12 valve and 24 valve engines. We recommend the use of pyrometer and boost gauges in conjunction with a larger exhaust when using these injectors.
Bully Dog Fuel Pin: Additional 40 horsepower for the Dodge 1988-1993 12 Valve Dodge Cummins
 Easily realize an extra 40 hp from your Dodge with VE injection pumps by installing one of our ALL new fuel pins. Simple installation, along with a solid horsepower increase makes this one of our hottest new products.
Bully Dog Valve Springs: Engineered to be the absolute best money can buy
These higher tension springs help prevent valve floating, which can occur on an engine that is producing over 50 lbs of boost. Taking this step is mandatory once a vehicle is upgraded with nitrous or a twin turbo set up. In high boost situations you run the risk of serious damage to your valves using stock springs.
Bully Dog Torque Plate: One of the most cost effective ways to increase horsepower
Designed to fit the 12-valve, 1994-1998 Dodge Cummins Diesel engines. Horsepower gains range from 30-100 depending on the year of the vehicle and transmission style.
Bully Dog J-Hook: A quick way to increase your boost

Available for the 2001-2002 24 Valve Cummins engine equipped with the 47RE automatic transmission. The J-Hook regulates the waste gate, facilitating greater boost numbers which rise even higher as performance modifications are added. The higher volume of air will also help keep exhaust temperatures down.
Bully Dog Big Fuel Kit: Increases fuel pressure and volume to the VP44 fuel injection pump.

The Big Fuel Kit eliminates the possibility of starving the injection pump when using high horsepower modules and injectors. Recommended for the 1998-2002 Dodges that have 400+ hp.
