need help, c63s coupe not showing 500 hp
my c63s coupe just hit 1800 miles today, so I decided to put her in sport plus and floor it past kick down at 65 mph, the engine data show 486 torque and 480hp for about 2 sec then goes down to 390tq and hp.. I tried it for a second time at 65mph past kick down and it got up to 500hp for 1 sec then goes back down to around 420 to 380. Put her in race mode and down shift to the lowest gear at 65mph and still the same story it'll show 500 hp and 516 tq for 1 second then goes back down to 380-475 hp/tq. I remember when I first took delivery of her, giving her 40 percent throttle in comfort felt brutal, not same the anymore.. Can anyone confirm if this is normal?

Few facts. You know the engine power rating is at the CRANK, right? So it'd NEVER have 500HP at the wheels
. And even if it did, that rating is under ideal conditions, meaning sea level, 68ºF, etc. Don't know how that gimmicky gauge works, but excluding the not insubstantial driveline losses, you lose about 3% power for every 1K' in elevation alone. And then you have other factors like gas quality and octane rating, etc. If you used a different gas station, it could be the issue. If car feels right, I wouldn't worry about that gauge.

And even if it did, that rating is under ideal conditions, meaning sea level, 68ºF, no humidity, etc., so for practical purposes, it'd never crank that much in real life.
