Hey everyone! New guy here from northern IL. I was sent here from another forum to PM Lextech for the file I needed and thought I should also introduce myself. I see this forum has loads of info that currently confuses me, lol. Had a few newer trucks that I installed tunes on using EFI live. I never actually wrote or edited any but I'm here to learn! My current rig is a 1978 Chevy Suburban K10 with a carb'd 400 but I got a hold of an L29 out of a '98 Suburban that I plan on building and dropping in with the 4L80e.
