Thanks for the welcome. I do have one question (sorry if its dumb) what exactly does an LS1 edit do? Is this better than a Nelson Tune? And also can you buy smaller pullys for the 5.3?

 

First off welcome to the site. LS1 edit is a computer program to modify diffrent parameters of your LS1 based engine computers. It is like getting a custom tune except you have to know what your doing. It's a very expensive program (to me anyway). I don't have Ls1 edit so I will let others tell you more about it.
