This java program allows you to enter your engine parameters and desired boost level, etc, and then plots the points on various compressor maps for you, in case you don't want to do all the calculations yourself. You can overlay different maps to find out what turbo and trim best fits your needs, or whether your current turbo is operating out of its efficiency range. It's pretty awesome.
