I bought and used a PSI harness and PCM from them and was happy with what I bought. The thing you will find if you call is that they will send you a "starter tune" with emissions turned off, VATS, etc, and the correct displacement programmed. They do not "tune cars", so you will still need to have a dyno or tuning shop take it from the baseline PSI sends you.
