I didn't think Titan tuned anything other than stand alone ems' anymore. They've got an amazing guy named Darin that does their tuning, but I'm almost positive they said no tuning afc's or other piggy backs. That may be why they told you 500 just to tune. I had my car tuned on the dyno locally here with an S-AFC for about 125. There's really not THAT much to it.
