I have seen several YouTube videos of tuned cars by Racechip and VR tuned.
1. Does it void warranty? As they modulate pre-ECU data, they seem to be plug and play. Can manufacturer or technical staff know by examining ECU logs, whether they have been working in the background?
2. Do they degrade fuel consumption? Well tuned chips makers and users claim improvement of consumption by keeping the car in low REV range in higher gears.
3. Decrease longevity of engine and transmission?
4. Any opinion about best module? Racechip looks promising as it has smartphone app for wireless management of profiles. However I have read in another member account here that it's functionality is questionable with DS. He has got better results with VR tuned
