While the DiabloSport didn't turn my C6 Corvette into a 500 HP monster (it has 400 HP stock), it did improve my overall experience. The car was prone to spark knock under light acceleration, and that's now gone. Mileage is up a little, too. Any HP increase is too small to notice. Shifts are a litte quicker, too. The USB cable did ship without a driver disk, and Windows XP didn't recognize the cable. I ended up using my own serial cable.
