WARNING!

DO NOT HAVE YOUR ECU REPROGRAMMED ANYWHERE BUT AT WEISTEC FOR

THIS SUPERCHARGER. THE AMG 55 USES AN ELECTRONIC THROTTLE CONTROL

(ETC), WHICH IS CONTROLLED BY THE ENGINE CONTROL UNIT (ECU) AND THE

CALIBRATION INSIDE. A REFLASH DOES NOT PROPERLY RECALIBRATE THE

ENGINE MANAGEMENT SYSTEM; THIS CREATES A DANGEROUS SITUATION THAT

COULD RESULT IN A STUCK THROTTLE AND CAN LEAD TO INJURY OR DEATH.

WEISTEC FULLY REPROGRAMS THE ECU TO MERCEDES STANDARDS, AND

ENSURES THAT ALL ENGINE SAFETY CONTROLS ARE FULLY FUNCTIONAL.
