Optimized Stock Tune Only Chassis Cab PowerStroke 6.7L F350-F550 (2011-2012)

The DuraMax Tuner DT1300230007000 is an Optimized Stock Tune designed for the 2011-2012 Ford F250/F350 6.7L Powerstroke, focusing on drivability and reliability while retaining the emissions system. It subtly sharpens throttle response, smooths out low-end performance, and helps reduce soot output. It supports custom hardware like larger tires or intakes and helps resolve common calibration errors such as TPMS mismatches. Combined with transmission tuning, it works to keep the truck in its powerband longer and prevents early or erratic shifting. It is accessible through HP Tuners RTD and VCM Suite without compromising factory safety limits.
