Product Information

RENNtech M157 Biturbo ECU Upgrades are TÜV approved!

Our intermediate level ECU upgrade for the Mercedes M157 engine still offers huge gains in performance across the entire RPM range, but with a slightly reduced peak HP and torque from our standard tune.

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. 

Our intermediate ECU tune increases performance from 556 HP and 550 lb/ft torque to 624 HP and 680 lb/ft at the crank! 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.

 

CLS 63 (C218) Stock Performance (Without Performance Package):

  • 518 HP @ 5500 RPM; 516 LB-FT @ 4800 RPM

CLS 63 (C218) Stock Performance (With Performance Package):

  • 550 HP @ 5500 RPM; 590 LB-FT @ 4800 RPM
  • Note: We have found the new M157 engine stock performance numbers vary from the baseline figures claimed by Mercedes Benz. We typically see slightly higher baseline numbers than claimed by the factory.

  • 638 HP @ 5500 RPM; 695 LB-FT @ 3800 RPM
