I was reading on another forum about these Pedal Box from DTE. They are German company and offer this for our cars as well as many other throttle by wire applications.

Ive used and seen similar products for motorcycles and they work . Im wondering if anyone on this forum has any experience with this product. At $ 300.00 if it improves the throttle response its something Id be interested in using.

Thanks for any info.

 

looks like its the same concept as sprintbooster...has mixed reviews, doesnt really add any power but basically presses down harder on the gas pedal...ive never had one installed but there are plenty of reviews on it

 

Yeah, I 've read that and sounds very interesting. He installed a similar device on his C320CDI and he claimed it makes the accelerator pedal feel like it's connected to the engine properly and takes away 99% of any built in lag.
I would like to hear more from C250 owners.

 

It has turned my lacklustre 2012 C250 into an enjoyable drive. It used to change up too quickly and labour along and a bit of lag. Now just a tweak on the loud pedal and it responds beautifully. Well worth the money IMHO
