But whats the reasoning for even tuning during the winter if you more concerned about how the car runs during the summer? Unless you run your car down ski slopes its not going to make a difference. And to be honest, your shit blow up so why are you giving advice in the first place? --- _[View the full topic](https://forums.speedlife.net/t/getting-tuned-during-winter-months/248924)._
