I think the entire premise of this is flawed. While using Mec boost and Nos your HP is not your limiting factor. You have more than enuf HP, I believe that TQ/weight is the best way to determine the tunes
I also think that this would be useful. Teamwork is hard (even harder when we cant see conversations from teammates while we were off when we log back on).
Advice! if your going to be using your car to pink with, you will likely be using boost and nos. In that instance, you should actually calculate the HP to Weight ratio of your car with the included HP from these things. P.S. Not all cars actually follow the idea of best ratio means best tune.
