🛠️ Why Calibrate Your M157?
Massive Torque Gains: The M157 is a "torque monster." Our Stage 1 adds over 100 LB-FT of torque, providing effortless overtaking power at any speed.
Optimized Engine Management: We modify Bosch MED17 maps, including boost levels, ignition timing, and fuel injection scaling, to safely increase output without bypassing factory fail-safes.
Refined Drive-ability: The car remains a comfortable, quiet cruiser in "Comfort" mode. In "Sport," the throttle response is sharpened to provide a more connected driving experience.
Improved Efficiency: By optimizing engine efficiency and reducing pumping losses, many owners see a slight improvement in MPG during highway cruising.
📱 Powergate 4: Professional Tuning at Home
We now offer the Powergate 4 (the evolution of the Powergate 3). This handheld device allows you to:
Flash via Smartphone: Use the Powergate App to install your custom ECUPROGRAM files via Bluetooth.
Cloud Storage: Your original stock file is saved securely in the cloud, allowing you to revert to factory settings at any time.
DTC Tools: Read and clear diagnostic trouble codes directly from the device.
🔧 Recommended Maintenance
To support 700+ HP, we recommend the following service items:
Spark Plugs: Upgrade to NGK 97506 "Step 1 Colder" plugs, gapped to 0.022".
Fuel: Strictly 93 Octane (98 RON) is required for advertised gains.
Cooling: Ensure your intercooler coolant levels are topped off, as the M157 is sensitive to heat soak.
