I was just discussing this with a dealer today. The PC III provides no advantage over the stick chip when using stock pipes or screaming eagles. Once you get outside those parameters, you may need it (or something like it) to get good performance from your pipes.russojerry said:It seems tha the power commander is popping up for sale everywhere. If it's such a good product why is everybody selling it off. I was cosidering buying one but am seriously questioning it at this point. Any insight would be greatly appreciated.
