Can someone explain to me if installation of Renntech tuner would void your warranty. Often members write the dealer flashed my ecu tuner. what does that mean? How hard are they to install. I live in the midwest near Saint Louis and have no idea who would install a tuner. Are there other tuners more powerful and with better track record. I looked at the brabus website but its too confusing . please help. Im a newbie trying to figure out if I should get one for the extra ponys. current 268hp. would like to push over 300hp? if you can answer my questions i would really appreciate it. are there any cons vs pros to consider?
