Ive been trying to find out whats wrong with my car since i too think my benz (500se euro) is lacking power. I tried to topspeed it but after i hit 100 m/h (160 km/h)it accelerated slow so i just took it to 110 m/h (175km/h).
Now that i read your post about it not reving out completley i know mine to doesnt at kickdown. I know the previous owner recently changed cams since the previous was worn out. Perhaps my chain to needs a tuning then. Havent bothered to take it to a mechanic yet since its not often you do those speeds but now when summer is coming up i want it to run good.
