EFI

I didn't touch the tune in the car all day.
That's awesome. Consistency is the name of the game and not having to do anything (at least engine-wise) to get the car to be consistent is huge. I suppose not having to mess with the tune might also result in fewer chassis changes as well. How would you predict your dial in that situation?

Out of curiosity, did you notice other racers making changes when the D.A. changed?
