How It Works — Our Tuning Process

Every EuroLab custom tune follows the same rigorous 4-step process.

🔍

1. Consultation & Health Check

We inspect your vehicle, check for fault codes, and discuss your goals. No tuning happens on a car with underlying issues.

📈

2. Baseline Dyno Run

Your car goes on our Mainline CCS3600 hub dynamometer for baseline power and torque measurements — SAE J1349-corrected for honest, repeatable numbers.

🔧

3. Custom Calibration

We develop your tune file in-house, making iterative adjustments on the dyno. Fuel maps, boost targets, ignition timing — all calibrated for your specific car, mods, and NZ 98 RON fuel.

✅

4. Final Validation & Handover

Final power pulls to confirm gains, data review with you, and a road test. You leave with your dyno sheet and a car that performs exactly as promised.

BMW G87 M2 Tuning FAQs

How much power does a tuned G87 M2 make?

With EuroLab’s MHD custom dyno tune, the G87 M2 (460hp stock) typically makes 600–640hp at Stage 1. Stage 2 pushes to 680hp. The G87 uses the same S58 engine as the M3/M4 — same tuning potential in a lighter, more compact package. All figures SAE J1349-corrected.

How much does it cost to tune a G87 M2 in Auckland?

MHD OTS (self-flash) is ~$993 for the S58 license plus $189 for the WiFi adapter. EuroLab’s MHD custom dyno tune is $2,500 incl. GST. xHP transmission tune (OTS) from $769. All G87 M2 models require FEMTO unlock ($2,800) as they are all post-June 2020 production. If the ECU has received a dealer software update, a bench unlock ($575 incl. GST) is also needed.

Does the G87 M2 need a FEMTO unlock?

Yes — all G87 M2 models require FEMTO unlock as they are all manufactured after June 2020. The FEMTO unlock costs $2,800 and requires the ECU (DME) to be physically sent to our Auckland workshop. If the ECU has also received a BMW dealer software update, a bench unlock ($575 incl. GST) is required.

Is the G87 M2 the same engine as the M3/M4?

Yes. The G87 M2 uses the full S58B30 twin-turbo inline-6 from the G80 M3 / G82 M4, detuned slightly to 460hp (vs 510hp Competition). With a Stage 1 tune, the M2 reaches 600–640hp — making it faster than a stock M3 Competition in a lighter body.

Manual or auto — which is better for tuning?

Both receive the same ECU tune and power gains. The 8-speed auto benefits from xHP transmission tuning (faster shifts, raised torque limiters). The 6-speed manual is the purist’s choice. For outright acceleration, the auto is faster; for driving engagement, the manual wins.

What supporting mods does the G87 M2 need for Stage 2?

Stage 2 on the S58 requires catless or high-flow downpipes and a charge pipe upgrade. No intercooler upgrade is needed for Stage 2. We stock and fit all supporting hardware at our East Tamaki workshop and carry parts from brands like Wagner Tuning and VRSF.
