Adrenaline HQ has proudly partnered with Weistec Engineering and now offers in house ECU tuning for a wide variety of Mercedes Benz powerplants, expanding on our previous Mercedes diesel tuning line to offer even more performance for our customers. 

The Weistec M274 ECU upgrade for the 2015+ C300 provides gains across the entire powerband resulting a vehicle that is more fun to drive in all driving situations.  The M274 ECU upgrade can be paired with our M274 Downpipes for further improved response and engine feedback.  

KEY FEATURES:
•    Increased HP and Torque (+7HP and +22 TQ with stock exhaust, +15HP and 45 TQ with race exhaust)
•    Improved Throttle Response
•    Optimized Fuel and Spark

ECU Tuning Process: 

Option 1 – Send your ECU to us.  We will tune it at our shop and will ship it back to you ready to install in your car.  
Option 2 – Bring your car to us and have us tune your car while you wait.  Most tunes are performed the same day and can be scheduled with minimal lead times.
