🔧 M178 ECU PERFORMANCE TUNE – AMG GT / GTS / GTR / GTC 🔧

Custom-tailored performance tuning for Mercedes-AMG M178-powered vehicles

💡 Why Choose Our Tune?

We specialize in maximizing safe, usable power for AMG GT owners who demand excellence. This isn’t a generic flash—our M178 tune is carefully calibrated to match your build, fuel type, and driving goals. Whether your AMG is stock or upgraded with downpipes, intakes, or intercoolers, our tune will bring the best out of it across the entire powerband.

• Safe, reliable gains with no overboost or knock-prone strategies
• Custom maps for 91, 93, or 100 octane
• Adjustable throttle response, boost targets, and burble intensity
• Tailored to your mods and driving environment
• Includes MyGenius handheld programmer for easy flashing

📈 Power Gains

Our M178 tunes consistently outperform across the curve. Expect:

• +120 to +150whp on tuned GT/GTS/GTR with downpipes
• Torque gains of 130–170 lb-ft, improving drivability and response
• Optimized for track or street, not just dyno numbers

🎯 Tune Options

You will receive up to 3 custom maps based on your build:

• 91 Octane (California-safe)
• 93 Octane (max power on pump)
• 100 Octane (track / race fuel)

We walk you through the process, review your vehicle specs, and help you choose the ideal burble intensity, rev limiter settings, and boost levels.

💬 What Customers Say

“Picked up serious torque down low. Feels like a different car entirely. Burble is tasteful, not obnoxious. Very happy with the support and tune.”

“Ran 10.4 @ 134 on 100 octane and sticky tires. Car pulls like a monster but drives smooth daily. This is how it should’ve come from the factory.”
