Can someone explain this to a newbie? I couldn't find the stupid questions thread, so I am posting this here. What does this do exactly, and how? And should one do this while the car is still under warranty?

BNR Tune 2011-2016 Limited Chevrolet Cruze 1.4L Turbo
The what it does and how I'm not going to be a lot of help with. I'd assume it adjusts the timing, fueling, and turns the boost up. For the warranty, I think if that is a concern of yours you are best not to mod. Technically the dealer would have to prove that the mod caused the issue to occur. For example, if it blows the turbo, they'd have to say that the tune was the reason the turbo exploded. However, it's a lot easier for them to blame the tune than it is for you to prove that it isn't the tune. I know personally, that is why I've held off modding my diesel. I don't want to risk the warranty.
