Coming with just over 500 horsepower, the Mercedes GT-S AMG is a beast with its 4.0L Bi-Turbo engine.  Doing a ECU Flash on these vehicles can gain you nearly 100 horsepower for reliable, powerful, and for a insanely fun driving experience.  The Bosch MED17.7.5 ECU can only be tuned by remove it from the vehicle and doing a bench flash.  This requires speciality tools such as the CMD or Alientech to be able to read and write the vehicle tuning data.  As we have tested here on our Mustang AWD Dyno, our baseline run had the peak torque at 3300rpm making 430ft/lbs where now 3300rpm makes 510ft/lbs and peak torque goes to 526ft/lbs at 3700rpm.  3700rpm has a gain of 100 ft/lbs of torque over stock!  This gain in torque continues which tapers down to redline while still making 60ft/lbs of torque even at 5000rpm.  6100rpm is making around 50ft/lbs.  Horsepower is a very linear increase starting at 3300rpm with 40awhp and climbing up to a peak of 70awhp over stock.  This is about a 90bhp gain on 91octane which is very good.
