There are plenty of performance upgrades for the fuel system available for the
early Cummins engines. If you've upgraded your fuel pump and injectors, then your factory turbo is letting you down. You can convert that unburned fuel back into usable power and performance. A performance turbocharger delivers substantial increases in airflow and boost which increases horsepower and torque
on the 1988-1993 5.9L Cummins powered Dodge Ram trucks. You'll appreciate the
increased throttle response, increased pulling power, lower EGT's and an extra
edge for off-highway performance.
