Engine Output Comparison
As indicated, the Green Diesel tune achieves a broad gain over the torque curve giving the driver a huge improvement in the drivability and “seat of the pants” feeling of the vehicle. Coupled with the transmission tune to hold gear to lower engine rpm, the torque is more usable throughout the rpm range. The driver has more responsive and intuitive control as it relates to the accelerator pedal and chosen gear.
Also, the max power of the engine is achieved as soon as possible with the hot tune and maintained over a plateau as wide as possible (roughly 700rpm). This gives a noticeable gain in the performance feeling of the engine while accelerating.
