I thought 08s had 600 HP at the fly wheel. How does yours get 560 RWHP? That is less than 7% drive line loss
Maybe engine tolerances or break-in procedure, not sure, but that's what it dyno'd with ~1200 miles on it bone stock. The only thing I've done to this car since that time is install spring caps, a MGW shifter and knob, and I had the mufflers replaced with a straight pipe, but that seemed to make the car lose power. I just wanted it to sound a little more angry than stock, and am happy with it, even if I did lose some power as a result.
