Why Kingaroy trucks need this work
Most Kingaroy owners who ask about tuning aren't chasing a dyno number — they want the transmission to stop hunting between gears towing up from Nanango, Wondai and Murgon, or the throttle to respond properly at low revs pulling away from a boat ramp or a set of lights. A conservative, towing-focused calibration fixes that; a big power claim that ignores the factory cooling system just creates a heat problem on the next long climb.
What's included
- Baseline scan and fault code check before any calibration is touched
- Supporting hardware assessed first — cooling, intake, exhaust, tyres
- Calibration matched to towing, touring or daily use, not a generic power map
- Transmission shift calibration matched to the engine tune
- Emissions equipment kept intact and functioning — no DPF or AdBlue deletes, ever
| Complaint | Tuning fix | Also check |
|---|---|---|
| Transmission hunts gears towing | Shift calibration matched to load | Cooling and torque converter condition |
| Dull throttle response low down | Towing-focused throttle mapping | Fuel and boost system health |
| Speedo/shift points wrong after bigger tyres | Tyre size correction | Diff ratio and speedo accuracy |
| Wants more power for towing | Conservative EGT/boost-aware tune | Factory cooling capacity limit |
Getting here from Kingaroy
Our workshop is at 46 Regent St, Caloundra — 2 hours from Kingaroy. Most Kingaroy customers drop the truck off in the morning and collect it the same day where the job allows, so diesel tuning doesn't cost you a second trip. If you're coming in from Nanango, Wondai and Murgon, call ahead and we'll have the hoist free when you arrive.
Fixed-price minor servicing starts at $469 (1500-series) and $599 (HD-series). All other work — including tuning & performance — is quoted before we start, with no surprises on the invoice.
Frequently asked questions
- Is tuning legal for trucks registered in Kingaroy?
- Legal tuning that keeps emissions equipment functioning and doesn't affect ADR compliance is fine. Tunes that delete or bypass DPF or AdBlue systems are illegal for road use in Queensland and are not something we offer.
- Can a tune fix my truck hunting gears towing out of Kingaroy?
- Often yes, when the hunting comes from a mismatch between throttle mapping and shift points under load. We check supporting hardware first, since cooling is usually the real limit on a hot climb, not the calibration.
- Do you take customers from Kingaroy and the South Burnett?
- Yes — it's around two hours to our Caloundra workshop, and we book Burnett customers as a single planned visit so the trip is worth making.
- What should I tell you when booking from that far away?
- Your model, engine, approximate kilometres, towing loads and any symptoms. That lets us allow the right time and have common parts on hand.
