AutoUpgrades Performance Tuning

The BMW i8 is already complicated enough. Naturally, we’ve made it faster. 🇩🇪

An extra 35 hp and 80 Nm from the petrol engine gives this German hybrid a little more urgency:

▪️ Power: 231 → 266 hp
▪️ Torque: 320 → 400 Nm

Behind those gains is coordinated calibration of torque requests, boost targets and load limits, with the factory closed-loop boost control and wastegate control maps retained.

Watch for the drive and a look at the engineering behind it. Full debrief included.

Mitsubishi C**t Ralliart Tuning

The 4G15 MIVEC Turbo now delivers stronger acceleration and a broader, more responsive torque curve throughout the operating range. Factory: 154 hp / 180 Nm Calibrated: 185 hp / 216 Nm

• 31 hp increase • 36 Nm increase • Full-load lambda targets recalibrated • Ignition advance increased by approximately 1° at high load and high engine speed • Engine torque limiters recalibrated • Factory protection strategies retained

In a compact, rigid chassis weighing only 1,140 kg, you notice every single additional horsepower.

Auto Upgrades | Performance ECU Calibration

The Mazda engineers gave us an outstanding platform.

We simply recalibrated the OEM strategy to let it deliver more of what it was always capable of.

Factory Output • 260 hp • 380 Nm

Calibrated Output • 320 hp • 470 Nm

Calibration Highlights • +60 hp • +90 Nm • Driver torque request recalibrated • Engine load limiters increased by up to 164% • Throttle control recalibrated • Full-load lambda targets re-engineered • Turbo control strategy completely re-engineered • Sustained boost pressure significantly improved • Wastegate duty cycle optimised • Factory speed limiter removed

The result is a far stronger pull through the entire rev range, with smooth factory-like drivability and OEM protection strategies retained.

2018 Porsche 911 Carrera S.
Another 50 horsepower and 110 Nm unlocked through a complete OEM ECU recalibration.
"We can't mention names... but somewhere in Zuffenhausen there's a calibration engineer who knows exactly who he is.
We've just done his job for him.
No need to thank us."
Calibration highlights: • +50 hp / +110 Nm • Torque limiters +26 to 30% • Engine load limiters up to +200% • Boost request +12% • Ignition timing +1.2 to 2.28° • Lambda and EGT models recalibrated • 309 km/h speed limiter removed
Performance. Engineered.

Audi A3 1.8 TFSI recalibrated.

Factory: 180 hp / 250 Nm
Calibrated: 230 hp / 350 Nm
Gains: +50 hp / +100 Nm

Calibration changes included:

• Torque and load requests recalibrated
• Boost and wastegate control recalibrated
• Fuel-rail pressure and full-load fuelling recalibrated
• Transmission torque limits coordinated with the revised engine torque model
• Shift times reduced by 40%

The result is substantially stronger acceleration with faster, sportier gear changes.

2016 Audi SQ5 3.0 BiTDI Tuning

Another diesel that punches well above its weight.

This 2016 Audi SQ5 3.0 BiTDI left the factory with 322 hp and 650 Nm. After a full recalibration of the OEM torque model, it now produces 377 hp and 745 Nm while retaining smooth, factory-like drivability.

Key calibration changes:
• Power: 322 → 377 hp
• Torque: 650 → 745 Nm
• Turbo pressure increased by 6%
• Torque model and limiters recalibrated (up to ~800 Nm)
• Smoke limitation strategy re-engineered
• Injection quantity increased by 5%
• Factory speed limiters removed

The result is a much stronger mid-range, effortless overtaking and seamless power delivery that feels exactly as though it left the factory that way.

Mercedes-Benz GLE63 S AMG (W166) Stage 2 Tuning.

Back in the workshop with this monster.

This Stage 2 calibrated GLE63 S AMG is now producing 700 horsepower and 950 Nm of torque on 98 RON fuel.

Unlike the last GLE63S we featured, this one also received a transmission calibration to allow the increased engine output, improving torque capacity, shift strategy and overall drivability.

The result speaks for itself. Brutal acceleration with OEM-style calibration philosophy and factory safety strategies retained.

Mercedes-Benz GLE63S AMG Tuning

Mercedes left a fair bit on the table.

• 585 hp → 685 hp (+100 hp)
• 760 Nm → 900 Nm (+140 Nm)

Calibration includes:

• Torque model recalibrated
• Boost pressure optimised
• Full load fuelling and component protection recalibrated
• Speed limiter removed
• Factory diagnostics and protection strategies retained

Optional VGS4 transmission calibration:
• Internal torque limiters recalibrated
• Faster, cleaner gear changes
• Optimised torque intervention during shifts
• OEM thermal management and protection strategies retained

It's still German engineering.
Simply slightly more... German. 🇩🇪

2016 Mitsubishi Pajero Sport Tuning
The Pajero Sport Finally Found the Sport.
Factory: 181 hp | 430 Nm Tuned: 221 hp | 495 Nm
For this 2016 Mitsubishi Pajero Sport equipped with the 4N15 2.4L turbo diesel, we developed a calibration focused on improving drivability, mid-range performance and overall refinement without compromising OEM reliability.
• +40 horsepower • +65 Nm of torque • Up to 32% higher torque request through the mid-range • Revised torque limiter coordination • Removed emissions-related torque troughs for smoother power delivery • Optimised boost pressure and fuelling by approximately 6% • Stronger towing, overtaking and everyday drivability • Factory diagnostics, thermal protection and safety strategies retained • Calibrated within Mitsubishi's OEM control strategy • A little more German intent.
Peak numbers are easy. Making it drive like it should have from the factory is the hard part.

Mercedes E-Class Tuning at Its Finest
Over-Engineered, Then Re-Engineered.
Factory Output • 382 hp & 530 Nm
Becomes • 412 hp & 580 Nm
This W212 Mercedes-Benz E500 retains everything that makes it such a composed, refined grand tourer while delivering substantially stronger performance.
Calibration work included: • OEM torque model re-engineered • Driver demand recalibrated • Engine load requests optimised • Variable valve timing adjusted • 11 ignition and related calibration maps fully recalibrated
OEM protection systems retained: • Knock control • Thermal management • Torque monitoring • Factory diagnostics • Original safety strategies
The objective was not simply to add power. It was to improve engine response, torque delivery and outright performance without compromising the refinement expected from an E-Class.
382 horsepower was good. 412 horsepower is better.
Factory refinement remains non-negotiable.
