You are in the right place. I have been lurking on here for quite some time trying to learn how to do things to my tbi truck. The LT1s are a bit tricky, because they flash like a newer vehicle rather than swapping chips. Let us know how you do, I have an LT1 I want to swap into a truck someday. Learning Tunerpro well takes some time, try not to change too much at first until you're comfortable with the program, and always save the clean bin that's not changed from factory settings. You will need it at some point. Best of luck!
