Since 1977 we continue to provide the best parts and service for diesel trucks. You can’t have a reliable high performance diesel engine without this extra attention to detail. We provide parts, service, diagnostics, repairs, and tuning for Commercial Diesel Trucks including Cummins, Caterpillar and Detroit Diesel. They are then tested, checked for leaks, and calibrated to match flow. If the customer wants to keep their original set of injectors, we can perform what we call a “clean and check” where they are disassembled, cleaned, and reassembled with new O-rings. Now the owner-operator has a blueprinted set of injectors all match flowed. First we do the leakage test to check the barrel and plunger tolerance, check the plunger to injector cup for leakage and seating, and then the recalibration to increase the flow for more horsepower, and then adjust the top stop setting.
Our new injectors are from Cummins ReCon. For injectors, we like to setup and blueprint every set of new injectors. Some users upgraded their big cam I engines with pulse manifolds just to get this increased performance.

We work with the customer to pick the best code for each application and set it up according to their needs. There are thousands of pump codes for different horsepower and torque curves. It then goes on the pump stand to be tested. We then reassemble the pump with new springs, gaskets, seals, and O-rings. With the pumps we start off by disassembling them, cleaning, and replacing all worn parts. With the added exhaust flow, the turbo makes boost quicker and the turbo boost sensor records this and sends the signal to the ECM, allowing the fuel to be delivered.
Many ask us what all goes into rebuilding fuel pumps and injectors. If you never had the pleasure of driving a truck equipped with one of our performance Big Cam Cummins NTC-855 engines, you have been missing out.
