RENNtech M157 Biturbo ECU Upgrades are TÜV approved!
Our intermediate level ECU upgrade for the Mercedes M157 Biturbo 4-MATIC engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.
This is ideal for customers who want increased performance in their daily driver without worry of extra strain on driveline components or for areas and countries with extreme altitudes, temperatures or fuel quality concerns.
This is a slight reduction from our standard tune but still offers white knuckle performance at one of the most affordable price points in the tuning market.
