W204 Tuning Box Advice

[Vik250]

Newbie here, recently bought a W204 C250 and have been thinking to purchase a tuning box.

I've come across the DTUK® CRD-T+® and also a unit from Chip Express.

Can anyone recommend one please?

I'm looking to have the extra power there when needed but mainly the economical gain.

Are these units "safe" for the engine? I have one year warranty with the MB dealer and like the fact of being able to remove the unit when needed so thought it would be more ideal for me than a remap.

Any advice appreciated, thanks

Look at TDI tuning.
I have used their boxes in several cars for over a decade and never had any issues. Last box was in a car for four years before i sold it.
I just emailed them as i just bought a 2 year old c220 coupe and they say they have recently had one developed.
I always get good mpg gains and power.
