Based on the 323 dyno, there was about a 2.7% increase in HP and a 2.9% increase in torque. If those amounts held true it would mean about a 7 HP (255 to 262) and 6 ft/lb of torque (220 to 226) increase for a 330.
BTW, did anybody notice the dyno for the 2005 Acura TL? It only dyno'ed at 205 HP and 187 ft/lb of torque. This for a car rated at 270 HP. That's a 24% decrease from the stated HP.
