Common Problems Fixed

EGR, DPF and AdBlue faults kill performance and trigger limp mode — we fix them at the ECU level.

We've earned the trust. Here's how.

After remapping thousands of diesel engines — LandCruisers, Rangers, Amaroks, BMWs, Mercedes — we know exactly what each engine can handle and where to draw the line. Every map we write is backed by 15+ years of real-world dyno data. Not guesswork. Not generic files. Your car, your engine, tested and proven on the day.

Factory file backed up first

Before we touch anything, we read and save your original ECU calibration. If you ever need the factory map back — for dealer service, warranty, or resale — we restore it in minutes.

How we handle factory warranty →

Dyno baseline before changes

Every vehicle goes on our in-house dyno before the remap. We measure actual wheel power and torque — so the gains you see are real, measured on your car, that day.

Safety limits respected — always

EGT limits, injection pressure ceilings and boost targets are hardcoded into the calibration. The engine always has accurate sensor data. No shortcuts.

No physical parts changed

No new injectors, exhaust, turbo or intercooler. We write new calibration data to your existing ECU — everything else stays factory. Your engine is unchanged physically.

Fully reversible, any time

Your factory file is stored securely. A full restore takes 30 minutes. No trace, no evidence — ready for dealer service, a trade-in, or a warranty claim.

Developed for daily driving

These maps are used by tradespeople, families, grey nomads towing caravans and people who bought $70k+ vehicles because they needed them to last. Conservative, reliable, proven.

Our process

How we remap

A professional remap is a structured process — not a plug-and-play box. Here's exactly what happens on the day.

01

Vehicle diagnosis

We scan the ECU for existing fault codes and check engine health before anything else. We only tune healthy engines.

02

Dyno baseline run

Your car goes on our in-house Mainline dyno. We record your factory power and torque at the wheels — the real, honest numbers.

03

Factory file backed up

We read and save your original ECU calibration before any changes. You can always go back to factory — fully reversible.

04

ECU maps tuned

Fuelling, injection timing, boost targets, torque limiters — all adjusted in coordination, specific to your engine and its current condition.

05

Dyno retest

Back on the dyno with the new map. We validate power gains, AFR and EGT under load. You see the before/after numbers on paper.

06

ECU lock + final check

The ECU is locked, the vehicle is road-tested, and the dyno sheets are handed to you. The whole process is typically one day.

    No extras. No surprises.

    Just the remap. Stock everything else.

    Most diesel owners think a power tune means a shopping list — new exhaust, bigger intercooler, upgraded injectors, a 3-inch downpipe. It doesn't. Years of calibration development on our Sydney dyno means we deliver the same real-world power and torque on a 100% stock your diesel as a comparable car running thousands of dollars in aftermarket bolt-ons. The fuel savings, the daily-drive smoothness, the long-term reliability — that's the brief we tune to.

    • Works with your factory exhaust

      Years of calibration development mean we extract the same real-world power as setups running aftermarket headers, cat-backs and bigger downpipes. Save the $1,500–3,000.

    • No injector, turbo or intercooler upgrades

      Stock hardware handles every gain we sell. We tune within the factory injection, boost and EGT limits — never beyond them.

    • Built for everyday driving

      School runs, the daily commute, weekend towing, highway cruising, occasional bush track — that's where our tune lives. Not a race-track special.

    • Long-term reliability is the brief

      Conservative EGT targets, dyno-validated AFR, factory-grade injection pressure. The tune is designed to be invisible 99% of the time and felt the 1% you ask for it.

    Who it's for: Aussie drivers who use their your diesel every day — for work, the kids, the caravan, the trades, the occasional weekend bush trip. If you want a race-tuned engine ready for the drag strip, that's not us. If you want your daily diesel to feel like it should have from the factory, that's exactly us.

    Got my Ranger PX2 tuned here. Massive difference in throttle response and pulls way harder up hills with the caravan. Workshop is spotless and the lads explain everything. Worth every cent.

    Booked online, dropped the car off in the morning, picked it up after work. Honest quote, no upsell, and the difference in my Q5 is night and day on the freeway.

    Drove down from the Central Coast for these guys and it was worth every km. Smoother, stronger, and using less fuel on my run home. Highly recommend to anyone with a diesel.

    Had my LandCruiser 200 Series tuned. Completely transformed — towing my horse float is effortless now. These guys know diesels inside out. Factory file backed up, zero risk.

    BMW X5 30d done. Was nervous about voiding warranty but they explained everything, backed up the original file, and the result on the freeway is outstanding. Fuel economy actually improved.

    My D-Max had a DPF and remap done the same day. No drama, no upsell, dyno sheets handed over when I picked up. The before/after numbers speak for themselves.
