Hi all, first post. I am pretty new to tuning. I had the jb4 on my c43, i now have a 2019 facelift c63s, I have a eurocharged ecu tune, but I have yet to swap out the cpc. I havent noticed any gains from the tune alone. My MB dealer told me they will install the Weistec CPC and "turn their head" to any tunes, problem is I already have the ecu tuned. If I would have known the dealer would install a full stage 1 weistec tune I would have done that and never worried about warranty issues.

My question is, my service manager sounded real cool with the thought of beginning with just the weistec cpc installed by them, seeing how I enjoy it, and not flagging my car for any tune. Is it okay to run a EC tuned ecu and a Weistec tuned CPC?

Yes it will work; the Weistec CPC is not meant for any specific brand-name tune, it is simply an unlock for the car's power limits.
