2019 GLC43 AMG EUROCHARGED ECU TUNE
i got my GLC43 in september and i finally got a ECU tune from EUROCHARGED canada.
the car feels more eager to finish the gears, but i notice that when i hammer it at the light from full stop in sport+ and esp fully off, it has a little moment of “breathing” and at the light at full stop it idles not regularly.
any ideas?
