As discussed by other members, the throttle lag in Comfort mode is horrible.

I also hate switching the modes every time I start the car to get it into Sport mode.

Which throttle response module would you recommend? Pros and Cons?

1) 2014 to 2021 MERCEDES C Class Sprint Booster V3 ($289 USD)

2) 2012 + Mercedes BMS Pedal Tuner - Adjustable throttle response ($179 USD)

3) Any other recommendations?

Your right foot…

But seriously though: A throttle response module will likely be of little help for your issue. What you are experiencing is the RPM shift points for comfort mode coupled with the automatic gear kick down when you want to get on it. The former changes with driving mode, with Sport+ holding the highest rpms when just cruising. The latter does not change by selecting the driving mode. A throttle response module will not remedy these issues - as that is the purpose of the driving modes coupled with the downshift paddle (or even with double pull on the paddle) or sticking with manual mode.

I too am looking for something to fix the lag in my pedal. It seems Mercedes dropped the ball on this one. Pulling out of a gas station when coasting slowly or simply trying to go at all after putting it in driving after reversing feels like the car shut off. The communication from the pedal to the computer is horrible. I’ve heard the BMS is pretty good, but I also heard that there are others out there that are better.. but anything would be better than the factory programming from the factory. Go to YouTube and search for Pedal Tune by Flexx Alexander. He kinda describes what he feels the difference is with and without the pedal tune.

And yes.. you will have all of “the pros” commenting on this post telling you that it’s a waste of money and a worthless mod etc etc. Im not sure what model they own, but I’m with you in this one. The pedal lag in these cars is awful and a Pedal Tune WILL definitely help. It’s just finding the right one. I’ve owned GM cars that have better pedal response lol.

this is why you set up Individual

Sport transaxle so pedal lag is gone. (sport + holds the gears longer and makes some pop/bang noise, but the pedal is the same)
ESP Sport so the car can wiggle a bit. Normal is a harsh nanny.
Sound Off
Sport + suspension Setting
As a bonus, it also kills the stop/start nonsense.

Get in car. Start. Push select once forward. Done. You'd turn off the stop/start anyway probably.

The best way to change the throttle response is via Vediamo or DTS Monaco.

What are these and why are they better?
