All Integrity Plus electronic injectors are calibrated to verify total volumetric flow and total flow variation between injectors after performance modifications are made. Variations during calibration are corrected, meaning each set is essentially a "matched set of injectors" that insure cylinder-to-cylinder balanced fuel flow. This process is very labor intensive, much like cylinder head port matching to insure air flow variation between ports. However, the serious performance-minded diesel owner understands that there are no short cuts to high-quality precision engine components. In fact many of the suppliers of these "high-flow" injectors do not even have the equipment to flow-verify complete injectors and are why they sell injector tips alone, their experience and investment is less.

12 Valve Dodge Products


The Cummins B 5.9 was introduced in 1984 as an agriculture engine. It was not until 1989 that it became the first B-Series Cummins engine to be used in a light duty truck; the Dodge Ram. The B 5.9, also known as the "12 Valve", became a popular alternative to the V8 engines typically used in these trucks, as it generated nearly double the torque at low engine speeds and nearly doubled the fuel economy as well. Mid-year in 1991, the B 5.9 received an intercooler. The 12 valve featured Bosch Direct Fuel Injection utilized a VE injection pump between 1989 - 1993, and a P7100 injection pump between 1994 - 1998. The 12 valve 5.9 remains one of the most popular engines in the market, despite being replaced by the 24 valve ISB midway through the 1998 model year.

Available Products Include:
Performance Injectors: 40, 50, 90, 100, 120, 150hp Upgrades
3200 RPM Governor Spring Kit for VE Pumps, and many others available

24 Valve Dodge Products


In 1998, the BT 5.9 was redesigned as a 24 valve engine to updated emission requirements. ISB stands for Interact System B. The ISB featured a Bosch VP44 rotary injection pump until 2003, when the injection system was upgraded to a Bosch high pressure common rail fuel injection system, which increased power output. In 2001, a high output (HO) version of the ISB became available, which slightly increased the output of manual transmission equipped trucks. A 610 version of the ISB became available which pushed torque to 610 lb-ft. Well known for its low speed torque, the Cummins 5.9 ISB has an advantage over V8 diesel engines in the light duty truck market.

Available Products Include:
Performance Injectors: 40, 50, 90, 100, 120, 150hp Upgrades
50hp VP44 Pump
Performance Nozzles: 50, 90, 100, 120, 150hp Upgrades

Common Rail Dodge Products


The 6.7 L Cummins is the latest in the B-series engines, introduced mid year in 2007. Rated at 350 HP & 650 lb-ft, it is also the most powerful B-series ever offered. The 5.9 ISB was replaced by the 6.7 to meet strict new diesel emission requirements. To meet such requirements, the 6.7 is equipped with an EGR (exhaust gas recirculation) system, a variable geometry turbocharger (VGT), and a diesel particulate filter designed to reduce diesel particulate matter by more than 90 percent. A new, higher-pressure version of the Bosch direct injection system is used.

Available Products Include:
Performance Injectors: 50, 90, 100, 120, 150hp Upgrades
100, 120, and 150hp CR Injectors
Performance Common Rail Pump
Performance Nozzles: 50, 90, 120, 150hp Upgrades

6.6 Liter Duramax Products


The 6.6 L Duramax, also known as the Duramax 6600, displaces 6.6 L and has been made available in several different versions. Between 2001 - present, 4 versions of the Duramax 6600 were available; the LB7, LLY, LBZ, & LMM. Specifications for all versions of the popular Duramax are available on this site. Duramax Diesel Specs now includes specifications and information for the cutting edge 4.5L Duramax 4500 LMK.

Available Products Include:
Performance Injectors: 50, 90, 120, 150hp Upgrades
Performance Common Rail Pumps
Performance Nozzles: 50, 90, 100, 120, 150hp Upgrades

6.5 Liter Chevy Products


The 6.5 L GM diesel was introduced in 1992, replacing the 6.2 L in 1993. Also manufactured by Detroit Diesel, the 6.5 was available in several versions to serve several different applications. The 6.5 L, like the 6.2 L, focused more on providing a fuel efficient diesel alternative. A special "Fuel Miser" version of the 6.5 surfaced in P-trucks (delivery trucks for bread/snack food companies) that produced the fuel mileage of a four cylinder. The 6.5 was offered in naturally aspirated & turbocharged versions.

Available Products Include:
40hp Injector Upgrades
Remote Mount PMD Bracket
Remote Mount PMD Complete Kit
40hp Nozzle Upgrades

7.3 Liter Ford Products


Changes to the 7.3 liter engine in 1994 gave birth to the 7.3 liter Power Stroke. By 1999, International had built 1 million 7.3 Power Strokes, and the 2 millionth 7.3 was built in 2002. Unfortunately, the 7.3 failed to meet stricter emission requirements and was therefore replaced early in 2003 by the 6.0 liter Power Stroke. The 7.3 is largely responsible for making the Power Stroke name legendary, as well as fueling the performance race between the big three.

Available Products Include:
Compressor Wheel Upgrade
Performance Injectors: 50, 100, 120, 150hp Upgrades.
Performance Nozzles: 50, 90, 120, 150hp Upgrades
