    • Mercedes-AMG GT 63 S 4-door 0-60 time before and after Weistec W.1 M177 ECU tuning software - 2.91 seconds

      This is a very simple before and after 0-60 test. The stock X290 Mercedes-AMG GT 63 S 4-door 4Matic+ is plenty quick to 60 miles per hour thanks to the 577 horsepower M177 twin turbo 4.0 liter V8 variant. The 590 lb-ft of torque certainly helps get things moving.


      Thanks to all wheel drive traction is not a problem. The stock run produces a very impressive 3.21 second 0-60 sprint as you can see above. Hustling 4500+ pounds that quickly to 60 on street tires shows how far things have come.

      Now with just the edition of the W.1 Weistec tune the 0-60 drops by 3/10's. All on 91 octane pump fuel:


      In other words, that is three car lengths just from a tune by 60 miles per hour.

      We of course want to see the difference in 1/4 mile elapsed time and 60-130 results but that is easily over half a second picked up in either metric. Quite simply an excellent improvement over stock.
