RennTech Performance ECU+ Upgrade For Mercedes-Benz W221 S 63 AMG V8 BiTurbo

Description

Description:

RennTech HHT (hand held tuner) allows you the unlimited ability to switch between tuned and stock ECU programming and requires no ECU removal. RennTech proprietary tuning module stores both the RennTech tuned file and your vehicles stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU. Programming takes only a few minutes and the vehicle can be reflashed at any time as many times as you wish.

RennTech 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.

RennTech intermediate ECU tune increases performance from 563 HP and 594 lb/ft torque, to an astonishing 669 HP and 734 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
