Stage I with stock air intake and stock exhaust is 235 HP @ 5200 RPM and 260 ft-lbs torque @ 3600-4400 RPM.
Due to the way the programming was done to give max performance in a stock configuration, it is possible that the different intake and exhaust may actually limit the HP. The jury is still out on that one. Mopar Performance abandoned their CAI Project, as they could not predict or promise any significant power gains from it.
I am not down on intakes; I have an AirRaid on my GT. However, I am considering going back to the original paper filter and airbox configuration since installing the Stage I upgrade.
I also have a K&N drop in to use with the stock airbox. At some point, I hope to be able to get an answer on intake changes with Stage I and whether or not they hurt performance. The hints from MPP indicate that intake changes may lessen the effectiveness of Stage I.
