Not much you can do with a C300....Other then trade it in for a C63.

Congrats on joining the MB club. I have found the only way to maximize speed is to always drive in S+ and to drive in a consistent way so that the ECU gets accustomed to that pattern. You should start noticing you are holding gears longer which gives you better in-motion acceleration, and acceleration from a stop seems quicker, too.

On the flip side, you will burn more fuel and MPG will drop noticeably. Also, it's a pain that the car will not hold the S+ setting from start to start. But in my opinion, getting the best possible performance outweighs these drawbacks. Enjoy the ride.

Im selling a Racechip GTS black if you're interested! Its one of the more well known piggyback mods out there from doing research.
Sadly i sold my car before i could even get the time to install it. Its brand new but i can let it go for $500

I'm seriously interested in buying your RaceChip GTS. If, it is brand new. Please send me your contact info.

Without CANbus access it can only tune a fraction of what the JB4 can do for you.
