Tuning & Vehicle Upgrade Solutions

Precision Performance Engineering by I-Fix Autohaus

At I-Fix Autohaus, we provide specialised engine tuning and vehicle upgrade services for discerning drivers who seek enhanced performance, efficiency, and a more refined driving experience. Our services are rooted in precision engineering, motorsport-grade technology, and an uncompromising approach to quality and safety.

Whether you’re looking to extract more power from a turbocharged engine, improve handling dynamics for spirited driving, or increase towing performance on your 4WD or commercial vehicle, our team delivers tailored solutions based on your vehicle, objectives, and driving profile.

Our Capabilities

🔧 ECU Remapping & Engine Control Tuning

We perform advanced ECU calibration and remapping using industry-leading software and tuning platforms (e.g. HP Tuners, Alientech, EcuTek). Each remap is custom-developed to deliver:

  • Increased horsepower and torque across the rev range

  • Enhanced throttle response and smoother power delivery

  • Improved fuel efficiency with eco-tuning options

  • Removal of factory restrictions (torque limiters, rev limiters, speed governors)

  • Optimised gear shifting on automatic and DSG transmissions

All tuning is performed with a deep understanding of engine parameters and factory safety tolerances — ensuring performance gains without compromising reliability.

📊 Dyno Tuning & Engine Diagnostics

Our workshop is equipped to provide dyno tuning (via in-house or partnered dyno facilities), offering real-time performance testing with:

  • Torque and power curve mapping

  • Air/fuel ratio and boost level optimisation

  • Pre- and post-tune comparison reports

  • Knock detection and ignition timing adjustments

This allows us to verify results under controlled conditions and fine-tune performance with surgical precision.

🛠️ Mechanical Performance Upgrades

For clients seeking mechanical improvements alongside software tuning, we offer:

  • Air intake systems: Cold air intakes, panel filters, induction kits

  • Exhaust systems: High-flow cat-back, turbo-back, and sports mufflers

  • Turbocharger upgrades: Larger turbo installs, intercoolers, wastegate and blow-off valves

  • Supercharger installations (model-dependent)

  • Fuel system upgrades: Injectors, fuel pumps, fuel pressure regulators

  • Cooling systems: Upgraded radiators, oil coolers, transmission coolers

All components are selected based on compatibility, performance target, and long-term reliability.

⚙️ Suspension, Braking & Handling Upgrades

Performance isn’t just about power — it’s about control. We provide expert installation of:

  • Coilover suspension kits (adjustable height and damping)

  • Performance brake systems (big brake kits, slotted rotors, braided lines)

  • Sway bars and chassis braces for body rigidity and cornering performance

  • Wheel alignment and corner weighting for optimal handling balance

We tune the entire driving experience to deliver confidence, control, and dynamic capability.

🔩 Transmission & Driveline Enhancements

Ensure your powertrain can handle increased output:

  • High-performance clutches and lightweight flywheels

  • Transmission remapping (auto and DSG tuning)

  • Upgraded differentials (limited-slip, locking)

  • Driveshaft and CV axle upgrades for high-torque applications

🚙 4WD & Diesel Performance Tuning

For diesel and 4×4 owners, we offer specialised tuning to:

  • Increase low-end torque for towing and off-roading

  • Improve throttle response and drivability under load

  • Optimise boost control and fuel delivery for safe power gains

  • Support EGR and DPF management solutions (compliance-dependent)

We understand the demands placed on workhorses and recreational 4WDs — and tune accordingly.
