Hello! So, I have a RennTech ECU tune on the way, and I was curious if anyone knows if the slight bump in power, and the elimination of the speed governor, will allow it to go over 200 mph in a safe and closed environment. Prior to the tune, the car seemed to be able to get over 180 mph without much issue at all, so I'm wondering if the gearing and other factors will let it exceed the 200 mph barrier.

Has anyone done it or have experience with it on a U.S. spec C63 Black Series?

Thank you,

Where can you do this at? I would like to test my car

If you have the Aero package that won't help with a top speed trial. Regardless, I think it's probably top out in the 190s somewhere compared to other AMGs with their aerodynamics and power levels. 🤷‍♂️

what hardware mods are you pairing the software to Mitch?

with everything else stock, you'll have zero gain in peak power, OEM software already maxed out the peak-power potential of the OEM hardware on our BS..

you might see some gains over the power-band & along the curve on dyno, but no peak power gain.

There is a video from Carwow where a BS went 203 mph I believe, but it was supercharged and didn't say what tune, I believe other then the supercharger it was stock. Without a supercharger it should still be able to go over 200, but would take a long runway I believe.

Evo Sport had one of their CLK BS hit 207 mph with a tune and exhaust goodies

Thats Acids car at MSL, far from stock 😄 It’s stage 3 Weistec build with additional cooling mods. Plus that was 200+ in 1/2 or full mile

Definitely full mile. These need about 1,200-1,300hp minimum and lots of traction to hit 200mph in a half mile.
I'm hoping to hit 170mph in a half mile run with ~740chp/625whp, but need to dial in some cooling mods and a better tune first.
