Well said. Plus, the feeling of a better responding throttle (vs the muted stock Z throttle response) is huge in this car, even for a daily driver. SB is a great budget option for those that can't spend the money on a tune.

In the end, you're talking about hundredths of a second. I'm not saying it doesn't matter. But it probably doesn't matter for most people

Yes I agree with you. I will want to do more mods and a tune but I worry about Nissan obsesion on mods nullifying the warranty. The car is brand new, when warranty is done "if I still have the car" I will definitely tune and dyno it.
