My earlier post on Stage 2 woes mentioned that I am considering a Stage 2 with the low/mid rpm range cams. What should I expect as far performance, gas mileage, etc. I already have a Stage 1 with the usual air filter and exhaust change, as well as the remap; done at the dealer. The more I know about the Stage 2, the more knowledgable questions I can ask them about it.
