Cheap Performance Upgrades for the C400
I am looking to add some minor and noticeable boost to the C400. Preferably the best piggyback tunes as i'm not looking for anything dramatic. Faster and less lag when accelerating are my focus. Thanks for any suggestions you provide.
Thanks,
I am happy to learn it can be used for a long time without much issues. How does it compare to the dinan tune ? In terms of performance gains ? I took a look at JB4 and observed it seems to offer more options and upselling add ons.

The tuning is awesome! Much power 0-60 in 4.2 seconds.
Have mine OBD tuned now, but was super happy with the Kleemann

i liked everything about the Kleemann! There was nothing negative for me, only get the OBD by a friens who is working for a tuning company
and our ECU’s normally had getting opened to tune, but OBD is better (warranty etc.)
So the Kleemann is def good and leaves no traces when you take it out off the car.

OBD tuning isn’t thst long available for our car ! So the Kleemann was the perfect solution to tune without opening the ECU for a flash!
now OBD tuning is possible so went to that!
have the OBD tuning now 2 weeks, great power over the whole RPM range. 0-60 what i meassured is about 4.5 secs so not as fast as the Kleemann
