27+ years of hands-on vehicle experience
More usable torque, sharper response and an automatic gearbox that works with the engine—not against it. ATM calibrates the complete vehicle in our state-of-the-art Mossel Bay dyno facility, backed by 27+ years of hands-on vehicle-building experience.
01 · Establish the truth
Before we add a single kilowatt, we measure how your vehicle arrives. A controlled baseline gives us the truth about its current delivery—and the reference for every decision that follows.
02 · Protect the original
Using leading professional ECU tools, we read and retain the original file before calibration begins. That gives us a secure starting point and exact access to the software in your vehicle.
03 · Build your calibration
Boost, torque and fuelling are calibrated together—not chased as separate numbers. The result is usable torque, clean response and confident overtaking that still feels composed every day.
04 · Complete the package
As part of the featured package, the EGR command is switched off and its related fault codes are removed from the ECU calibration—cleanly integrated into the same file.
05 · Remove the ceiling
Where the platform supports it, the factory speed limiter is removed within the same calibration, so the ECU package is complete when it is written back to the vehicle.
06 · Match the automatic gearbox
The autobox is calibrated around the new torque delivery. Shift timing, response and torque management work together, so the vehicle feels stronger and more settled—not simply more powerful.
07 · Prove the result
The finished calibration is tested under load on our in-house dyno. We compare the baseline and final curve, refine the delivery and verify the change on the same vehicle, same dyno and same session.
08 · The handover
More usable power. More torque where you drive. Sharper response and a gearbox calibrated to match. This example finishes at 195 kW and 620 Nm; your vehicle leaves with its own verified result.
Demonstration figures. Your result is measured from your own vehicle—not taken from a catalogue graph.
Build my packageThe ATM calibration standard
ATM accesses the vehicle correctly, secures its original software and builds the calibration around the exact ECU, gearbox, hardware and intended use—then verifies the finished result under load.
The confidence behind the calibration
For 27+ years, ATM has built, repaired and calibrated vehicles from the inside out. That judgement—combined with a state-of-the-art dyno facility, leading professional tools and ATM’s international calibration network—is what turns software changes into a vehicle that feels properly sorted.
No plug-in box or generic file. Compatibility and final output are confirmed from the exact ECU, software, hardware and vehicle condition.
Real vehicles · measured decisions
Power is only useful when the complete vehicle is working correctly. These completed ATM projects show four different starting points—and why the right answer is not always simply more software.
2019 BMW X4 M40i · B58
The BMW arrived already tuned, but excessive heat behind its restrictive factory catalyst showed that pushing the software harder would be the wrong decision. SNIPER corrected the restriction with a high-flow downpipe; ATM then recalibrated the complete vehicle on the dyno.
These figures belong to the individual vehicles shown. Results vary with platform, software, hardware, fuel and condition; ATM measures your vehicle rather than promising a catalogue number.
SNIPER Racing · In-house fabrication
ATM and SNIPER work under one roof, so the restriction is corrected and the hardware is completed before the final calibration. From complete stainless systems and downpipes to valved systems, boost pipes and one-off fabrication, every component is built around fit, flow, sound and the way you use the vehicle.
Valves closed for a restrained daily drive, long trips and passengers—without giving up the flow and finish of a properly built system.

Results become reputation
Beyond the calibration
Restriction, heat, airflow and hardware capacity all change what a vehicle can deliver. ATM and SNIPER can solve the complete system—from emissions-component removal and pipework to larger hardware, calibration and final dyno verification.
01 · DPF software and hardware
On supported diesel vehicles, we remove the DPF core, complete the exhaust work and recalibrate the ECU so regeneration requests and the related DPF fault logic are switched off with it.
02 · EGR calibration
The EGR command is switched off and its related fault codes are removed inside the vehicle-specific ECU file. It is completed as part of the calibration—not left as an unresolved warning-light problem.
03 · Catalyst and downpipe
Where the build calls for it, SNIPER completes catalytic-converter removal and fabricates the downpipe or connecting exhaust work around the actual vehicle—then ATM matches the software to the finished hardware.
04 · Turbo upgrades
A larger or upgraded turbo changes airflow, boost control, fuelling, heat and torque delivery. We plan the supporting hardware around the intended result and write the calibration for the turbo that is actually fitted.
05 · Intercooler and boost pipes
Intercooler upgrades help manage charge temperature while stronger, correctly routed boost and intercooler pipes keep the airflow path dependable. SNIPER fabricates the supporting pipework to suit the vehicle and the rest of the build.
06 · Complete performance build
From turbo and intercooler to downpipe, full exhaust, boost pipework and the final ECU or gearbox calibration, the complete combination is planned together and verified under load before handover.
Supported software and fabrication options
Not every vehicle needs a complete build. ATM can include the exact additional software or fabrication work the supported platform requires, while keeping the final package coordinated under one roof.

Plan the pipework →ATM Chiptuning + SNIPER Racing · Built in Mossel Bay
Every vehicle comes to us for a reason: more confidence when overtaking, stronger towing torque, sharper response or hardware that finally works as one complete package. ATM Chiptuning and SNIPER Racing bring calibration, dyno verification and custom fabrication together under one roof—so your vehicle leaves feeling properly finished.
ATM Chiptuning
From hard-working Hilux, Ranger and D-Max bakkies to Land Cruisers, European performance cars and daily drivers, every ATM calibration is shaped around the vehicle, its hardware and the way you use it—then tested on our in-house dyno until the result is right.
SNIPER Racing
A proper performance system should fit, flow and sound like it was always meant to be there. SNIPER Racing hand-builds stainless exhausts, downpipes, boost pipes and intercooler plumbing in-house—each one shaped around your vehicle and finished with pride.
Before your vehicle arrives
The exact platform still decides the final scope, but these are the questions vehicle owners ask us most before booking.
No. The N90 Hilux is the visual demonstration. ATM supports many modern ECU-controlled petrol and diesel bakkies, SUVs and performance vehicles, subject to the exact ECU, gearbox and software.
No. A plug-in or piggyback box remains external to the ECU and alters selected signals. ATM establishes professional access to the vehicle’s control software, retains the original file and writes the confirmed vehicle-specific calibration into the ECU—without leaving an external tuning box in the vehicle.
No. Where a supported platform allows professional OBD access, ATM can communicate with and unlock the ECU through the vehicle’s diagnostic connection without opening the control unit. Other platforms require a different professional access method; ATM confirms the correct route from the exact ECU and software.
Vehicle-specific ECU calibration, automatic gearbox calibration, EGR switched off with related codes removed, speed-limiter removal where supported, retention of the original ECU file, professional ECU access where required and final dyno verification. No plug-in tuning box is fitted.
Usually, yes. Hardware changes alter airflow, boost control, temperature and torque delivery. When a build includes supporting hardware, ATM and SNIPER complete the agreed physical work first and then write the final calibration around the combination that is actually fitted.
For performance calibration work completed on the dyno, ATM records the vehicle’s baseline and final delivery so you can see the measured change from your own session. The exact test and verification format is selected for the platform and work completed.
Yes. On supported vehicles, ATM and SNIPER can complete the required physical DPF or catalytic-converter work and match it with the correct ECU calibration so the hardware and software are completed as one job.
Yes. On supported vehicles, the EGR command is switched off and the related EGR fault codes are removed within the vehicle-specific ECU calibration.
Yes. ATM can plan turbo and intercooler upgrades, while SNIPER fabricates the supporting boost and intercooler pipework in-house. The finished hardware combination is then calibrated and verified as one system.
Yes. SNIPER Racing fabricates complete stainless exhaust systems, high-flow downpipes, custom mufflers, X-pipe layouts and supported valved systems in-house. A valved build can remain restrained for daily use and offer a fuller exhaust character when opened.
Yes, where the exact vehicle and software support the requested strategy. Send the vehicle basics through the quick enquiry and ATM will discuss the relevant options, required physical work and correct scope with you.
No. They are representative figures for this website journey. The result depends on the exact vehicle, software, hardware, fuel and condition, and is measured on your own session.
Some drivers see improved consumption when added torque lets the vehicle work with less throttle. Actual economy depends heavily on vehicle condition, load, route and driving style and is never guaranteed.
Yes. ATM assesses the software and the hardware actually fitted, identifies restrictions or mismatched components and then develops the correct calibration around the complete combination. The BMW B58 case above is an example of correcting the underlying restriction before recalibration.
