Yes, it's very possible to over gear the car!

Is there a magic number? Not really. But in general a 4.08 gear would be great for an N/A car if you don't mind the extra revs on the highway.

For a FI car it's probably best to stick with the stock gearing as it will surely overpower the low 4.08 ratio on street tires.
