DME Tuning vs Race Chip
I am thinking of installing the Eisenmann muffler & downpipe for my M5 and wanted to either use an Race chip or do a DME tune.
My friends are suggesting that I go with DME+JB4 which translate to stage 2 but for me I don't want to pay for 2 tunes.
I just want my car to be in the safe zone without me worrying about parts breaking down. What I like about the RC is that I can remove it whenever I want which isn't the same with DME as I need to send my ECM to them
Which one is better for people who have tested either one ?
