was able to get mine to 161 with a tune

Khan 55

I share the M113 motor so might as well chime in. Don't know weight difference between me and a C55. I did 257km/h after my wife pushed it at 245 whilst I was asleep. I told her no ways you gona go faster than me so after the next stop, I took the wheel and pushed it to 257. Didn't go more but engine didn't sound like it was limiting. Just wouldn't push more. Had ample of road ahead. Caught an S500 and raced the guy. He had to give way to me at 180 or so km/h. Was head of him by 5 car gap or so and he couldn't catch nor could I open more

Fastest I got my c55 was 135mph stock on this curvy road. One of the best day in my life. Car felt like it was glued to the road.

I regularly reach the electronically limited max (257 km/h) on the autobahn, will soon be getting the eurocharged tune though
