The Case STX 375 runs a 14.9 litre Cummins QSX15 engine. We have the ability to read out the factory ECU / ECM data and re work the software to adjust power, torque and fuel usage along with many other core functions. The STX375 is the same as the New Holland TJ375 so of course we can tune them both.
