I find that shifting at 4k is good. It still shows you have a sports car but its not burning fuel like crazy. Anything lower than 4k makes my drive boring(it just a nuetered car then). I tend to get between 25-27 mpg with this shifting scheme.
I've always head shifting at 3rd gear is the most economical place, but I usually shift a little past 4000 rpms... it's mid-way to the red-line and keeps the drive interesting... plus i still get great gas mileage. The way I look at.. you bought this car for a reason, have fun!
