Manufacturers always rate horsepower at the crank, power at the wheels (Fron Wheels in the case of the 3) is less due to driveline losses.

My car just tested at [email protected], so assuming the 160 Crank HP is accurate 20HP is lost through the transmission & other driveline components.

What kind of Dyno and was that corrected or uncorrected? Ambient temps also??? Can you post the plot?

The 20 whp loss is about right... It is pretty well documented that Miatas typically see about a 26 hp difference between an engine dyno and the number from dynojet.
