If you aren't already setup to tune yourself, and don't already have a harness and are jumping straight to turbo... listen to this guy, Term X is definitely the easier route.
I will be setup to tune GM PCM's for various reasons regardless, so I started with a GM ECU and a PSI Harness, but once I go bigger boost (2-3 years from now) I'll use my harness and PCM for another project and likely go Term X just for the built in functionality.
