For starters, a reminder that a stock Type R is specified as making 306 horsepower and 295 pound-feet of torque.

Hondata's FlashPro kit costs $695, and for that sum you get the following gains:

- With 91 octane gasoline: 33 hp, 39 lb-ft.
- With 93 octane: 47 hp, 72 lb-ft.
- With E25 (25 percent ethanol): 58 hp, 78 lb-ft.

Here's a dynamometer graph showing a stock Type R vs. a car programmed with the 93-octane tune. Note that the stock Type R's output was better than advertised. So that puts total output of the Hondata-flashed car at 364 horsepower and 404 pound-feet.
