WEISTEC M157 Biturbo ECU Upgrade


As an industry leader in tuning and calibration, Weistec Engineering is proud to introduce the much anticipated ECU tune for the bi-turbo M157 vehicle lineup. After months of painstaking dyno and road tuning, we are proud to introduce the most powerful ECU upgrade ever released for the M157 engine. Fully developed in house, our ECU tune has surpassed the 600 wheel horsepower mark on a completely stock vehicle with no other modifications.

After converting the naturally aspirated M156 motor to a forced induction application, the tuning of a factory forced induction engine is right in our wheelhouse. With a keen understanding for optimal running conditions for the M157, we have revised many features of the factory ECU programming which creates an astounding 608 horsepower and 660 torque at the wheels on California pump 91 octane. 

Key Features:

  • +139 Wheel Horsepower
  • +186 Wheel Torque
  • Eliminate Top Speed Limiter
  • Increased Throttle Response
  • Optimized Boost, Fuel and Spark
