I installed my lt's and high flowcatted midpipe and i had weld in flowmasters so you know my setup. After the install it was running ok but definatly rich. But now its just running like $hit so i need a tune. Anyone have any suggestions cause i need it right away its my dd and it was running even worse last night so i need a tune asap. So any site info and what i have to do would be great thanks. i have an xcal 3 btw.
