I would do the 93 tune FIRST and then decide if you want the E50 tune later. Then you know the process of datalog, upload, reflash, datalog, upload, reflash, etc.... before ALSO adding fuel mixing into the mix. I bet by the time my 93 tune is done I will be 4-5 tanks deep, maybe more, since this is my daily and the couple days back and forth and what not. And I think my "engine tune" revisions are on hold until we get my trans tune perfected, so its not just a quick one two back and forth, it can be 4-5 revisions back and forth...which is a GREAT aspect of this tune. He wants them perfect and that takes time.
