There's going to be no performance or economy increase in using the CS over the older Edge/Gryphon platform. Bill told me they use the same tunes. But, the CS DOES let you monitor a few more things and it definitely has more "bling".
One thing the CS and CTS platforms don't have at the moment is an Avg MPG readout, and Bill cannot program them to datalog like he can with the older Gryphon. Edge says they are going to add the Avg MPG PID once they work out some details on making it more accurate.
I'm really puzzled though about your RPMs. What is your idle set at? If the engine is idling faster than it used to, that would eat gas and, you could lower it using the custom options in the Edge.
I also think you could LOWER your part throttle upshift and downshift points by the max values (-2, -3, and -5, I think). AND, lower your part throttle Torque converter lock/unlock points by the max too. (-2, -3, -5, -10 is what I remember those values to be). Those changes will get you into higher gears sooner and keep you there longer, which will reduce the "rev" feeling you are experiencing.
As 88 said, I'd really stick with OEM coils AND plugs. I've heard of too many problems with other brands.
