🚗 Why spend hours travelling to a dealership?

Modern diesel 4WDs are more advanced than ever before.

Many repairs today require more than just a basic scan tool. Accurate fault diagnosis, module programming and software updates often require specialist manufacturer-level diagnostic equipment.

For many people in the Whitsundays, that has traditionally meant a long trip to a dealership.

At Dieselflash Whitsundays, we’ve invested heavily in advanced diagnostic equipment and software so we can perform many of these services right here in Proserpine.

Whether it’s:
✔ Engine warning lights
✔ Electronic faults
✔ Module programming*
✔ Drivability issues
✔ Diesel diagnostics

Our goal is simple…

Diagnose the fault correctly, recommend the right repair, and get you back on the road as quickly as possible.

Why spend hours travelling when expert diagnostics could be available much closer to home?

Ford F150 3.5 Twin Turbo – Stage 2 Results 🔥

We started with a Stage 1 tune on the factory setup and picked up an extra 25kw at the wheels.
The biggest restriction quickly became obvious — the factory intercooler was seriously underwhelming and holding the combo back.

So the hunt began for an aftermarket intercooler setup capable of supporting the power these twin turbo V6s are capable of.

After fitting the upgraded intercooler and refining the calibration, the results spoke for themselves 👌

• Stage 1 gain: +25kw at the wheels
• Final gain with intercooler upgrade: +53kw at the wheels
• Final output: 277kw at the wheels
• Stock turbochargers retained
• Huge improvement in intake temps and consistency
• Stronger power delivery across the rev range

And Lincoln’s happy as he’s now the quickest F150 of the North, don’t mind his version of Cowboy boots thou 😜

Yes we are Dieselflash… but if she’s a 4x4, we’ve got you covered 😉💪
