HD Tuning

When you’re hauling heavy, every bit of torque counts 👇

This 2012 Kenworth T409SAR with the ISX 14.9L was on the dyno for a custom HD Tuning calibration, focused on improving usable power and torque where it matters most.

As it arrived:
571.2 HP
2526.7 Nm

After tuning:
601.7 HP 🚀
2749.5 Nm 🚀
(All figures measured at the wheels)

More torque = less effort… and that often means better fuel economy too 💪

We’re not chasing numbers for the sake of it. Every change is tested and refined on the dyno to ensure safe, consistent, and reliable performance.
