Hey guys, I've been looking into tuning for a friend who has a vw passat and found this option. It seems NAAK builds tunes and uses Dimsport Genius handheld tuner to write the tune in the vehicle. Just wondering if anyone has used either of these brands. If so, I have a few questions. Does NAAK preload tunes when the device is purchased? Also does one device support multiple cars? Thanks for taking time to read this.
