You can safely redline the tach, if you mean going up to the redline. However I wouldn't be doing it with each and every upshift in the case of a Miata or any other car. But why do you have to in the first place? Once you get past peak power and torque, all rpm does is serve as an exceptionally weak testosterone substitute.
Does anyone have a link to a stock tq curve diagram for the N/A? Im very interested to see where the inclination really sets in.
