I wonder if the same theory applies to the normally-aspirated 3.2L. I would be surprised if the ECU / pulley combo provides similar yields (power gain), but then again, guess it wouldn't hurt to try (with the exception of the burning hole in my wallet).
I would truly appreciate some feedback from NA Crossfire owners with ECU / pulley modifications as well (boy.. this thread is already off topic!!)
