Just an update, I've done two tuning sessions on the '71 Cutlass I mentioned previously in this thread, with great success. I used the very limited XDF that I had (I need to find a hack for $85), and an A138.ADX that works great. I actually imported one of my dashes I created in a $59 ADX to use on his car last night while sitting in the passenger seat and reliazed that I hadn't done that yet. lol I think I got the ADX from moates.net fileman. It might have been an ADS that I imported to TP RT V5.
