Well, it looks like I now know what way I am going to go with my Firebird. I am going to be working on learning the JetDST system. I will admit, I am kind of nervous about it. Not a ton of information out there on it, and the information I can find is telling me to buckle up for a nightmare. Out of an abundance of caution, I haven't tried to write anything to my car yet. I ended up looking on here for a .cal file to read, and have been slowly working my way through the information, and trying to find what I am going to want to modify and what I won't need to worry about. Ton of work so far, but I am so excited.
