I've been self learning to tune for the past three years on a 97 modified LT1 and 04 GTO. Thanks to the help of this site and others I've gotten to look and learn of of many others tunes and why GM's computers due what they do, but the one thing has always troubled me and that is how to look at bins in Jet dst because so far all I can look at is cal and jcls. Please help, also I have many tunes to upload for sharing as I just found your website since monodax departed to cyber heaven..
