As a leader in tuning and calibration, Weistec Engineering is proud to release tuning packages for the naturally aspirated M156/M159 vehicle lineup. Our ability to successfully innovate and create the world's first 50 state legal supercharger system for the 6.3L AMG has allowed us to further identify and understand the complex factory modules.
We have created a strong yet reliable tuning solution that utilizes the same calibration technology that has been applied to our Supercharger System. With a keen understanding for optimal running conditions for the M156, we have revised many features of the ECU which creates an astounding 441 horsepower to the wheels on 91 octane.
Customers who purchase our ECU Upgrades will receive credit towards the purchase of any Weistec M156 Supercharger System, if you are thinking of supercharging your car in the future and are not ready for the purchase, this is a good way to not spend money twice, while making more power right away.
