HD Tuning

Big truck. Bigger numbers. 📈

This 2016 Western Star DD15 came in with an existing tune already on it. One that had been causing the owner a few headaches. Rather than patch it up, we started fresh, and built a calibration properly around the vehicle.

Then we put it on the dyno. Because that's what we do.

Stock ✅
Power 432.8 HP
Torque 2015.2 Nm

Tuned 🔥
Power 527.5 HP
Torque 2316.9 Nm

That's a huge gain of +95 HP and +302 Nm. At the wheels. On the graph. No guesswork.

Stronger pull under load, better throttle response through the rev range, and a properly calibrated engine that's not burning fuel unnecessarily. At today's diesel prices, that matters.

The owner's words said it all. Glad he came in. Glad it's done properly.

We dyno test every vehicle we tune ✅
Light vehicles to heavy haulage, one truck to a full fleet. Bring it in and let's see what it's got.
